A ray of light traveling in glass `(mu=3//2)` is incident on a horizontal glass-air surface at the critical angle `theta_(C)`. If a thin layer of water `(mu=4//3)` is now poured on the glass-air surfac, the angle at which the ray emerges into air at the water-air surface is

A ray of light travelling in glass (mu=3//2) is incident on a horizontal glass air surface at the critical angle theta_(C) . If a thin layer of water (mu=4//3) is now poured on the glass air surface, the ray of light emerge into air at the water air surface at an angle of pi//k , radians find the value of k.

A ray of light travelling in glass (mu_g=3//2) is incident on a horizontal glass-air surface at the critical angle theta_C. If a thin layer of water (mu_w=4//3) is now poured on the glass-air surface. At what angle will the ray of light emerges into water at glass-water surface?

A ray of light travelling in glass having refractive index _(a)mu_(g)=3//2 is incident at a critical angle C on the glass air interface. If a thin layer of water is poured on glass air interface, then what will be the angle of emergence of this ray in air when it emerges from water air inteface?

A ray of light travelling inside a rectangular glass block (mu=sqrt2) is incident on the glass-air surface at an angle of incidence of 45^@ . The refractive index of air is 1. The ray will
