A light beam is incident on heavy flint glass (n=1.65) at the polarizing angle. Angle of refraction is 31.22 degrees. If the ray reflected from the surface of the flint passes through a polarizing material with its polarizing orientation at 25 degrees to a normal of the flint glass surface, determine the change in the intensity.
