Question

A light ray is traveling from medium A to medium B. As it enters medium B, it bends toward the normal. What can you say about the speed of light in the medium?

Answer 1

Ф: angle before refraction
β: angle after refraction

Ф > β

sinФ > sinβ

The velocity is directly proportion to the sine of refraction taken from normal so

$\frac{sinФ}{sinβ}$ > 1

$\frac{v1}{v2}$ > 1

v1 > v2

The speed in the medium B is less than it in A
