Question

Why does Refraction occur ?

Answer 1

Answer:

We have learned that refraction occurs as light passes across the boundary between two media. The only time that a wave can be transmitted across a boundary, change its speed, and still not refract is when the light wave approaches the boundary in a direction that is perpendicular to it. .

Answer 2

the phenomenon of bending of light when it enters from one medium to another is called refraction of light
