Question

Why does light refract when it goes through a prism? How does the glass bend the light rays?

Answer 1

● light refracts when it goes through prism due to its structure
these have restangle surfaces.
●it bends due to

MATHEMATICAL REASON

as we studies in earlier classes

sini / sinr = constant
since
i will be more than r

2 REASON
WHEN light comes to prism
it bends due to their different speeds
when light came to prism it changes speed due to dufferent wavelenght and due to which its bend
