As shown in Figure P35.73, a light ray is an incident normal to one face of a 30°-60°-90° block of flint glass (a prism) that is immersed in water.
(a) Determine the exit angle θ3 of the ray.
(b) A substance is dissolved in the water to increase the index of refraction n2. At what value of n2 does total internal reflection cease at point P?
