Question

A ray of light passes from air to glass at an angle of 30 calculate the angle of refraction

Answer 1

here is your answer maTe

µ = sin i/sin r

Here, angle of incidence, i = 30

Therefore, sin i = sin 30 = 0.5

Given, µ = 1.5

Therefore, sin r = sin i/µ

Sin r = 0.5 /1.5 = 1/3

Therefore, r = sin -1 (1/3)
