Question

from a point source of light situated at a depth h in water Rays of light can emerge out in air only through a particular area of the water surface.

(1) draw a diagram and mark in it that circular path of water surface and its radius are given the refractive index of water u = 4/3

(2) calculate the angle of incidence of the day incident at any point on the circumferential line of the circular area .
[48°36'=sin^-1 0.7501]

(3) show that r= 3/ root 7 ×h
