Question

A light ray travels from a rarer to a denser medium. Will it move closer or away from the normal on the interface?​

Answer 1

Answer:

hy

Explanation:

if light travels from a denser medium to a rarer medium then it actually bends away from the normal as the speed of light increases as it enters the rarer(hence faster) medium.

When light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left. This behavior follows from Snell's Law. As you saw before, the larger angle must be in the medium having the lower index of refraction
