A point source of light is placed at a distance h below the surface of a large deep lake. (a) Show that the fraction f of the light energy that escapes directly from the water surface is independent of h and is given by f=(1)/(2)-(1)/(2n)sqrt(n^(2)-1) where n is the index of refraction of water. (Note: Absorption within the water and reflection at the surface, except where it is total, have been neglected) (b) Evaluate this ratio for n=4//3 .
