Question

The absolute refractive index of water is 4/3 what is the critical angle and absolute refractive index of glass is 3/2 find out the relative refractive index of water with rrs

Answer 1

Given that refrective index=4/3

Let critical angle=C

According to Snell's law

C=sin^-1(1/refrective index)

C=sin^-1(3/4)

C=sin^-1(0.75)

C=48.59°
