Question

22. The basic cause of refraction is
1 point
O when light is incident on a boundary
O
when the refractive indices of two
media are equal
O
the change in speed of light in going
from one medium to another
O None​

Answer 1

Answer:

option b

Explanation:

The cause of refraction of light is that light travels with different speeds in different media. This Change in the speed of light when it moves from one medium to another causes it to bend.

Answer 2

Answer:

hey mate! here's your answer:

Explanation: {option b}

Refraction is the phenomenon of bending of light at the boundary of two mediums.

Refraction is caused due to the change in speed of light when it enters from one medium to another.

e.g., 1. when light goes from air into water it bends towards the normal because there is a reduction in its speed

       2. when light goes from water to air it bends away from the normal because three is an increase in speed of light.
