Question

what is the cause of refraction of light when it passes from one medium to another ?​

Answer 1

Answer:

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.

Answer 2

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. ... The wavelength decreases as the light enters the medium and the light wave changes direction.
