Question

what is refraction of light​

Answer 1

Answer:

Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. ... Refraction is responsible for image formation by lenses and the eye.

Answer 2

bending of light ray on passing from one medium to another. if the light is passing from rarer to denser medium it bends towards the normal and when the light ray passes from denser to rarer medium it bends away from normal.
