In the figure a ray of light is perpendicular to the face ab of aglass prism (n = 1.44). a)Find the largest value for the angle f sothat the ray is totally reflected at the face ac if the prism isimmersed in air.
b)Find the largest value for the angle f o that the ray is totallyreflected at the face ac if the prism is immersed in water.
