Question

A ray of light is incident from air on a glass plate having thickness $\sqrt{3} cm$ and refractive index $\sqrt{2}$ The angle of incidence of a ray is equal to the critical angle for glass-air interface The lateral displacement of the ray when it passes through the plate is ___$\times 10^{-2} cm$ (given $\sin 15^{\circ}=026$ )

Answer 1

The correct answer is $52\times 10^{-2} cm$
