Question

Find the maximum angle of refraction when a ray of light is refracted from glass ( u 1.5 ) to air.

Answer 1

here is ur answer
hope it will help you

Answer 2

given :

μ= 1.5

As we know from critical angle definition :

sin θc=1/μ

sin θc=1/ 1.5

sin θc= 10/15 = 2/3

θc= sin⁻¹(2/3)

θc=41.81°
