Total Internal Reflection: A light ray enters a glass enclosed fish tank. From air it enters the glass at 20° with respect to the plane of the surface and then emerges into the water. The index for the glass is 1.50 and for water 1.33.(a) What is the angle of refraction in the glass?(b) What is the angle of refraction in the water?(c) Is there any incident angle in air for which the ray will not enter the water due to total internal reflection? If so, find it.
