[D]. It is reflected back
Q11
In a quiz competition, you are asked a question where you have to choose the statement which is/ are incorrect?
[A]. Hypermetropia is that defect of vision due to which a person cannot see the nearby objects clearly.
[B]. The near point of a hypermetropic eye is more than 25cm away.
[C]. Hypermetropia is corrected by using spectacles containing convex lenses.
[D]. The whole purpose of using a convex lens is to reduce the converging power of the eye-lens.
Q12
The stars twinkle but the planets do not twinkle at night because:
[A]. The stars are small but the planets are large
[B]. The stars are very large but planets are small
[C]. The stars are much nearer but planets are far off
[D]. The stars are far off but planets are nearer to earth
Q13

[A]. People who wear spectacles or have undergone cataract operation scan also donate Eyes.
[B]. The doctors of the eye bank team remove the eyes at the home of the dead person or at the hospital and it takes 10-15 minutes.
[C]. Those donated eyes which are not suitable for transplantation are used for doing research and for teaching purposes in medical colleges.
[D]. None of the above.
Q14
The danger signals installed at the top of tall buildings are red in colour. This can be easily seen from the distance because among all the other colours, the red light:
[A]. Is scattered the most by smoke or fog
[B]. is scattered the least by smoke or fog
[C]. Is absorbed the most by smoke or fog
[D]. Moves fastest in air
Q15

[A]. Both the eyes on the sides
[B]. One eye on the side and one at the front
[C]. One eye on the front and one at the back
[D]. Both the eyes at the front

[D]. Pupil
Q18
Consider the following statements and choose the incorrect one:

[B]. Two eyes at the back
[C]. Two eyes on the sides
[D]. One eye at the front and one on the side
Class 10 Science Chapter 10 Important Questions
What is the function of Iris?
Iris is a dark muscular diaphragm that controls the size of the pupil.
What is meant by accommodation of eye?
The ability of the eye lens to adjust its focal length is called accommodation.
Why do stars twinkle?
The twinkling of a star is due to atmospheric refraction of starlight. The starlight, on entering the earth’s atmosphere, undergoes refraction continuously before it reaches the earth.This makes continuously change in star’s position and we see the twinkling of stars.
Why does sky apear blue in colour?
The molecules of air and other fine particles in the atmosphere have size smaller than the wavelength of visible light. These are more effective in scattering light of shorter wavelengths at the blue end than light of longer wavelengths at the red end. When sunlight passes through the atmosphere, the fine particles in air scatter the blue colour (shorter wavelengths) more strongly than red. The scattered blue light enters our eyes and we see blue sky.
