Question

A ray of light is incident in water:
a) On a plane water-air boundary of incidence 45 °
b) On a plane water-glass boundary at an angle of incidence of 30°
Calculate the angle of refraction in each case.
(Refractive index glass=1.50, refractive index water=1.33)

Answer 1

Answer:

on a plant water air boundary of indence 45⁰
