Question

Explain refraction of plane wave front when gomg from rarer medium to denser medium

​

Answer 1

Answer:

To determine the shape of refracted wavefront, we will draw a sphere of radius v2τ from point A in the rarer medium. ... Since r > i (rays bend away from the normal on travelling from denser to rarer medium), the speed of light in the rarer medium (v2) will be greater than the speed of light in the denser medium (v1).
