The mixing of colours can be shown with the help of the diagram given in fig.

Light Long Answer Type Questions

Question 1.
Explain the image formation in plane mirror?
Answer:
A mirror with a plane surface is called a plane mirror. The ordinary mirror we use is a plane mirror. Formation of image is one of effects on reflection of light. The image is seen behind the mirror and it is of the same size as the object. The distance from the object to the mirror and the distance between the mirror and the image are equal. In the plane mirror the right side of the object appears to be left side of the image, and the left side of the object appears to be the right side of the image. This inversion of sides is known as lateral inversion.

Question 2.
Define Newton’s experiment?
Answer:
Newton’s Experiment:
The idea that sunlight consists of several colours was first put forward by Sir Isaac Newton. He passed a narrow beam of light into a prism. The light that emerged from the prism was found to be coloured as in a rainbow. He gave the name spectrum to this coloured patch of light. The spectrum was seen to consist of seven colours of light – violet, indigo, blue, green, yellow, orange and red. The various colours found in white light can be easily remembered as VIBGYOR. The process of splitting up of white light into different colours is called dispersion of light.

Question 3.
Explain rainbow?
Answer:
Rainbows are formed by sunlight falling on rain drops. The rainbow is always observed with the back towards the sun. The rainbow is formed when rain drops owing to refraction and internal reflection produce deviation and dispersion into seven colours of the sunlight falling on them. The rainbows are visible only when the altitude of the sun is less than 42°.

A full rainbow can be seen from an aeroplane flying at higher altitudes. It is a matter of common observation that when one looks at a spray of water on which sun shines, rainbows are seen. When you look at the water falls with the sun shining at your back, a circular rainbow will be seen. In a common rainbow (primary rainbow) the violet color is observed in the inner fringe and red on the outer fringe.

Question 4.
How will you show that combining seven colours, we get white light?
Answer:
Take a circular cardboard disc of about 10 cm diameter. Divide this disc into seven segments. Paint the seven rainbow colours on these segments as shown in Fig. (a). A small hole is made at the center of the disc. Fix the disc loosely on the tip of a refill of a ball pen. Ensure that the disc rotates freely [Fig.(a)]. Rotate the disc in the daylight. When the disc is rotated fast, the colours get mixed together and the disc appears to be whitish [Fig. (b)]. This disc is popularly known as Newton’s disc.

Why do we Fall Ill Long Answer Type Questions

Question 1.
Becoming exposed to or infected with an infectious microbe does not necessarily mean developing noticeable disease. Explain.
Answer:
Infected with a microbe does not mean developing a disease because an infectious microbe is able to cause a disease only. If the immune system of the person is weak but a person with strong immune system normally fights off microbes. We have cells which are specialised to kill the pathogenic microbes. These cells are active when infecting microbes enter the body and if they are successful in removing the pathogen, we remain disease – free. So, even if we are exposed to infectious microbes, the person will not catch the disease.

Question 2.
Give any four factors necessary for a healthy person.
Answer:
Factors necessary for a healthy person are as follows:

1. A clean environment with proper public health services.
2. Personal hygiene prevents infectious diseases.
3. A proper balanced diet and sufficient nourishment are necessary for good immune system of our body.
4. Immunisation / vaccination against severe diseases.

Question 3.
Why is AIDS considered to be a ‘Syndrome’ and not a disease?
Answer:
AIDS is considered a syndrome and not a disease because AIDS causing virus – HIV comes into the body via the sexual organs or any other means like blood transfusion and spread to lymph nodes all over the body. The virus damages the immune system of the body and the body can no longer fight off many minor infectious. Instead, every small cold can become pneumonia, or minor get infection can become severe diarrhoea. The effect of disease becomes very severe and complex, at times killing the person suffering from AIDS. Hence, there is no specific disease symptoms for AIDS but it results in a complex disease and symptoms.

Question 4.
(a) The signs and symptoms of a disease depend upon the tissues or organ the microbe targets. Explain giving any two examples.
(b) How does the immune system work against microbes?
(c) Name two diseases against which vaccines are available.
Answer:
(a) Disease – causing microbes enter the body through different means. These disease – causing micro – organisms are tissues specific or we can say that they target a specific organ.  If these microbes enter the body via the nose, the lungs are target and the symptoms are:

1. cough
2. breathlessness.

This is seen in the bacteria causing tuberculosis. If brain is targetted by these microbes, the symptoms will be headache, vomitting, fits or unconsciousness. This is seen in the bacteria causing meningitis.

(b) Immunisation is most important and effective way to raise resistance against the disease. Immunity may be two types:

1. Active immunity
2. Passive Immunity (artificial).

In active immunity, the body responds against disease – causing microbes and produces antibodies. The antibodies attack organ and kill the disease – causing microbes. In passive immunity, prepared antibodies are used against disease – causing microbes.

(c) We have vaccine against polio and tuberculosis.

Why do we Fall Ill Higher Order Thinking Skills (HOTS)

Question 1.
Why we cannot destroy virus?
Answer:
Virus attacks our body and consume proteins and RNA only. They do not have any metabolic pathway while other pathogens have their metabolic pathways. Our medicines stops the metabolic activity of pathogens and hence they get destroyed, but it is not possible in case of virus.

Question 2.
How vaccine stops disease while it is, itself a low dose of similar causative agent?
Answer:
Our body has a very strong immune system and it develops antigen to subside the effect of any new high quantity antibody entering in the body. Presence of chemical in small harmless quantity initiate development of antigen in body and when actually agent enters in the body, antigen fights easily with it.

Voice (वाइस)
वाच्य

Voice (वाच्य) क्रिया का वह रूप है जो यह बताता है कि subject (कर्ता) कार्य का करने वाला है या उसके प्रति कोई कार्य किया गया है।
Voice दो प्रकार के होते हैं –

(1) Active Voice और Passive Voice
जैसे – The hunter killed a lion-Active
शिकारी ने शेर को मार डाला।
The lion was killed by the hunter-Passive
शेर शिकारी के द्वारा मार डाला गया।

यहाँ, पहले वाक्य में कर्ता (subject) hunter कार्य करने वाला है इसीलिये verb “killed” Active voice में होगा। जबकि दूसरे वाक्य में subject lion’ के प्रति कार्य हो रहा है इसीलिये verb ‘was killed’ passive voice में होगा।

Active से Passive बनाना

(1)Active से Passive में बदलने के लिए ‘to be’ क्रियाओं का प्रयोग किया जाता है। सबसे पहले Object (कर्म) को Subject (कर्ता) के स्थान पर रखते हैं। इसके पश्चात् tense के अनुसार क्रिया ‘to be’ को फिर मुख्य क्रिया (verb) की 3rd form को रखते हैं और अन्त में कार्य करने वाले (doer) को शब्द by के बाद रखते हैं।

‘To be’ क्रियाएँ आठ हैं। बिना इनके passive नहीं बन सकता है।
Verb to be’.- is, are, am, was, were, be, been,being.
केवल transitive verb को passive voice में बदलते हैं क्योंकि उसका object होता है।

निम्न वाक्यों को पढ़ें –

Active – We like mangoes.
Passive – Mangoes are liked by us.
Active – The dog cought the rat.
Passive – The rat was cought by the dog.
Aetive – He is flying a kite.
Passive – A kite is being flown by him.

कभी-कभी कुछ nouns के दो objects होते हैं। Passive Voice में उनमे से किसी को भी Subject बनाया जा सकता है परन्तु अधिकतर Indirect Object को Subject की तरह प्रयोग करते हैं।

उदाहरण –
Active – He gave me a book.
Passive – I was given a book by him.
Or
A book was given (to) me by him.
Active – Ram told me stories at night.
Passive – I am told stories at night by Ram.
Or
Stories are told me at night by Ram.

पाठ्य-पुस्तक पृष्ठ संख्या # 159-160

प्रश्न 1.
पाठ्य-पुस्तक में दिये गये प्रत्येक चित्र में छायांकित भागों के लिए भिन्न लिखिए। क्या ये सभी भिन्न तुल्य हैं ?
हल :
(a) (i) छायांकित भाग = \(\frac { 1 }{ 2 }\)
(ii) छायांकित भाग = \(\frac{2}{4}=\frac{2 \div 2}{4 \div 2}=\frac{1}{2}\)
(iii) छायांकित भाग = \(\frac{3}{6}=\frac{3 \div 3}{6 \div 3}=\frac{1}{2}\)
(iv) छायांकित भाग = \(\frac{4}{8}=\frac{4 \div 4}{8 \div 4}=\frac{1}{2}\)
चूँकि \(\frac{1}{2}=\frac{2}{4}=\frac{3}{6}=\frac{4}{8}\)
अतः सभी भिन्नै तुल्य हैं।

(b) (i) छायाकित भाग = \(\frac{4}{12}=\frac{4 \div 4}{12 \div 4}=\frac{1}{3}\)
(ii) छायांकित भाग = \(\frac{3}{9}=\frac{3 \div 3}{9 \div 3}=\frac{1}{3}\)
(iii) छायांकित भाग = \(\frac{2}{6}=\frac{2 \div 2}{6 \div 2}=\frac{1}{3}\)
(iv) छायांकित भाग = \(\frac { 1 }{ 3 }\)
(v) छायांकित भाग = \(\frac{6}{15}=\frac{6 \div 3}{15 \div 3}=\frac{2}{5}\)
चूँकि \(\frac{4}{12}=\frac{3}{9}=\frac{2}{6}=\frac{1}{3} \neq \frac{2}{5}\)
सभी भिन्नै तुल्य नहीं हैं।

प्रश्न 2.
पाठ्य-पुस्तक में दिये गये छायांकित भागों के लिए भिन्नों को लिखिए और प्रत्येक पंक्ति में से तुल्य भिन्नों को चुनिए
हल :
आकृतियों द्वारा दर्शायी गयी भिन्न

उत्तर-तुल्य भिन्न
(a) → (ii),
(b) → (iv),
(c) → (i),
(d) → (v),
(e)→ (iii).

प्रश्न 3.
निम्न में से प्रत्येक में __ को सही संख्या से प्रतिस्थपित कीजिए

हल :

प्रश्न 4.
\(\frac { 3 }{ 5 }\) के तुल्य वह भिन्न ज्ञात कीजिए जिसका
(a) हर 20 है।
(b) अंश 9 है।
(c) हर 30 है।
(d) अंश 27 है।
हल :

प्रश्न 5.
\(\frac { 36 }{ 48 }\) के तुल्य वह भिन्न ज्ञात कीजिए जिसका
(a) अंश 9 है।
(b) हर 4 है।
हल :

प्रश्न 6.
जाँच कीजिए कि निम्न भिन्ने तुल्य हैं या नहीं

हल :
(a)∵ 5 x 54 = 270
और 30 x 9 = 270
∴ 5 x 54 = 30 x 9
अत: \(\frac { 5 }{ 9 }\) और \(\frac { 30 }{ 54 }\) तुल्य भिन्नें हैं।

(b)∵ 3 x 50 = 150
और 10 x 12 = 120
∴ 3 x 50 ≠ 10 x 12
अतः \(\frac { 3 }{ 10 }\) और \(\frac { 12 }{ 50 }\) तुल्य भिन्नें नहीं हैं।

(c)∵ 7 x 11 = 77
और 13 x 5 = 65
∴ 7 x 11 ≠ 13 x 5
अतः \(\frac { 7 }{ 13 }\) और \(\frac { 5 }{ 11 }\) तुल्य भिन्नै नहीं हैं।

प्रश्न 7.
निम्नलिखित भिन्नों को उनके सरलतम रूप में बदलिए

हल :
(a) \(\frac { 48 }{ 60 }\)
48 = 2 x 2 x 2 x 2 x 3
60 = 2 x 2 x 3 x 5 .
∴ 48 और 60 का म. स. = 12

(b) \(\frac { 150 }{ 60 }\)
150 = 2 x 3 x 5 x 5
60 = 2 x 2 x 3 x 5
150 और 60 का म. स. = 30

(c) \(\frac { 84 }{ 98 }\)
84 = 2 x 2 x 3 x 7
98 = 2 x 7 x 7
84 और 98 का म. स. = 14

(d) \(\frac { 12 }{ 52 }\)
12 = 2 x 2 x 3
52 = 2 x 2 x 13
12 और 52 का म. स. = 4

(e) \(\frac { 7 }{ 28 }\)
7 = 1 x 7
28 = 2 x 2 x 7
7 और 28 का म. स. = 7

प्रश्न 8.
रमेश के पास 20 पेंसिल थीं। शीलू के पास 50 पेंसिल और जमाल के पास 80 पेंसिल थीं। 4 महीने के बाद रमेश ने 10 पेंसिल तथा शीलू ने 25 पेंसिल प्रयोग कर ली और जमाल ने 40 पेंसिल प्रयोग कर लीं। प्रत्येक ने अपनी पेंन्सिलों की कौन-सी भिन्न प्रयोग कर ली ? जाँच कीजिए कि प्रत्येक ने अपनी पेंसिलों की समान भिन्न प्रयोग की है।
हल :
रमेश द्वारा प्रयुक्त की गयी पेंसिलों की भिन्न = \(\frac { 10 }{ 20 }\)
शीलू द्वारा प्रयुक्त की गयी पेंसिलों की भिन्न = \(\frac { 25 }{ 50 }\)
जमाल द्वारा प्रयुक्त की गयी पेंसिलों की भिन्न = \(\frac { 40 }{ 80 }\)


अतः प्रत्येक ने अपनी पेंसिलों की समान भिन्न प्रयोग की।

प्रश्न 9.
तुल्य भिन्नों का मिलान कीजिए और प्रत्येक के लिए दो भिन्न और लिखिए

हल :
(i)→ (d),
(ii)→ (e),

I am quite well here and hope the same for you. Today I will tell you about the picnic we had last Sunday.

Last week I went to Agra to my uncle’s place. There we decided to go for a picnic to Sikandra. I, with my three cousins, went to Sikandra last Sunday. We took some fruits, bread and other eatables with us. We reached Sikandra at 9 a.m. in the morning. It is Akbar’s tomb there. It is made of red stone.

There were lots of monkeys. We gave them nuts to eat. There were also deer and peacocks. After seeing the whole place we sat down to eat the eatables that we had. We sang songs and told stories. We enjoyed a lot. At 2 p.m. we thought of returning home. We reached home in a happy mood and felt quite fresh. I missed you there a lot. Rest is fine.

Yours affectionately,
Pawan

प्रश्न 1.
क्या \(\frac { 1 }{ 3 }\) और \(\frac{2}{7} ; \frac{2}{5}\) और \(\frac { 2 }{ 7 }\) तथा \(\frac { 2 }{ 9 }\) और \(\frac { 6 }{ 7 }\) तुल्य भिन्नें हैं ? कारण दीजिए।
हल :
(i) \(\frac { 1 }{ 3 }\) और \(\frac { 2 }{ 7 }\)

यहाँ, आकृतियाँ समान आकार की हैं तथा रेखांकित भाग आकृतियों का बराबर भाग नहीं दर्शाता है। इसलिए \(\frac { 1 }{ 3 }\) और \(\frac { 2 }{ 7 }\) तुल्य भिन्न नहीं हैं।

(iii) \(\frac { 2 }{ 5 }\) और \(\frac { 2 }{ 7 }\)

यहाँ, आकृतियाँ समान आकार की हैं तथा रेखांकित भाग आकृतिओं का समान भाग नहीं दर्शाता है। इसलिए \(\frac { 2 }{ 5 }\) और \(\frac { 2 }{ 7 }\) तुल्य भिन्नै नहीं हैं।

(ii) \(\frac { 2 }{ 9 }\) और \(\frac { 6 }{ 27 }\)

ये आकृतियाँ समान आकार की हैं तथा रेखांकित हिस्सा आकृतिओं का बराबर हिस्सा दर्शाता है। .
इसलिए \(\frac { 2 }{ 9 }\) और \(\frac { 6 }{ 27 }\) तुल्य भिन्नें हैं।

प्रश्न 2.
चार तुल्य भिन्नों का एक अन्य उदाहरण दीजिए।
हल :

इन आकृतियों का समान आकार है तथा रेखांकित भाग आकृतियों का बराबर भाग दर्शाता है। अतः \(\frac{1}{4}, \frac{2}{8}, \frac{3}{12}\) और \(\frac { 4 }{ 16 }\) तुल्य भिन्नें हैं।

प्रश्न 3.
प्रत्येक भिन्न को पहचानिए। क्या ये भिन्नै तुल्य

हल :
(i) दी गई आकृति भिन्न \(\frac { 6 }{ 8 }\) प्रदर्शित करती है।

(ii) दी गई आकृति भिन्न \(\frac { 9 }{ 12 }\) प्रदर्शित करती है।

(iii) दी गई आकृति भिन्न \(\frac { 12 }{ 16 }\) प्रदर्शित करती है।

(iv) दी गई आकृति भिन्न \(\frac { 15 }{ 20 }\) प्रदर्शित करती है।

अतः दी हुई आकृतियाँ तुल्य भिन्न प्रदर्शित करती हैं।

प्रश्न a.
रजनी कहती है कि \(\frac { 1 }{ 3 }\) की समतुल्य भिन्नें हैं

इत्यादि।
क्या आप उससे सहमत हैं? कारण सहित स्पष्ट कीजिए।
हल :
हाँ, तुल्य भिन्नों की संख्या काफी होती है, क्योंकि यह दी गई भिन्न के अंश और हर को समान संख्या से गुणा करके प्राप्त की जाती हैं। चूँकि प्राकृत संख्याएँ असीमित होती हैं। अतः तुल्य भिन्नों की संख्या भी असीमित है।

प्रश्न 1.
निम्न को सरलतम में लिखिए

हल :
(i) \(\frac { 15 }{ 75 }\)
15 = 1 x 3 x 5
∵ 75 = 1 x 3 x 5 x 5
∴ 15 और 75 का म.स. = 15

\(\frac { 15 }{ 75 }\) का सरलतम रूप = \(\frac { 1 }{ 5 }\)

(ii) \(\frac { 16 }{ 72 }\)
16 = 1 x 2 x 2 x 2 x 2
∵ 72 = 1 x 2 x 2 x 2 x 3 x 3
∴ 16 और 72 का म. स. = 8

\(\frac { 16 }{ 72 }\) का सरलतम रूप = \(\frac { 2 }{ 9 }\)

(iii) \(\frac { 17 }{ 51 }\)
17 = 1 x 17
∵ 51 = 1 x 17 x 3
∴ 17 और 51 का म. स. = 17

\(\frac { 17 }{ 51 }\) का सरलतम रूप = \(\frac { 1 }{ 3 }\)

(iv) \(\frac { 42 }{ 28 }\)
42 = 2 x 3 x 7
∵ 28 = 2 x 2 x 7
∴ 42 और 28 का म. स. = 14

\(\frac { 42 }{ 28 }\) का सरलतम रूप = \(\frac { 3 }{ 2 }\)

(v) \(\frac { 80 }{ 24 }\)
80 = 2 x 2 x 2 x 2 x 5
∵ 24 = 2 x 2 x 2 x 3
∴ 80 और 24 का म. स. = 8

\(\frac { 80 }{ 24 }\) का सरलतम रूप = \(\frac { 10 }{ 3 }\)

प्रश्न 2.
क्या \(\frac { 49 }{ 64 }\) अपने सरलतम रूप में है?
हल :
∵ 49 = 1 x 7 x 7
64 = 1 x 2 x 2 x 2 x 2 x 2 x 2
यहाँ उभयनिष्ठ गुणनखण्ड 1 है अर्थात् 49 और 64 का 1 के अतिरिक्त कोई उभयनिष्ठ गुणनखण्ड नहीं है।
∴ \(\frac { 49 }{ 64 }\) सरलतम रूप में है।
