Question

why does refraction of light take place​

Answer 1

The Cause of Refraction. We have learned that refraction occurs as light passes across the boundary between two media.

Refraction is merely one of several possible boundary behaviors by which a light wave could behave when it encounters a new medium or an obstacle in its path.

Answer 2

$\huge\mathfrak\purple{Answer-}$

⭐Refraction is the bending of wave when it enters a medium where its speed is different.

⭐Refraction of light takes place due to difference in speed of light between two or more media.
