The 45-45-90 triangular prism shown in the figure has an index ofrefraction of 1.43, and is surrounded by air. A ray of light isincident on the left face at an angle of 55.0°. The point ofincidence is high enough that the refracted ray hits the oppositesloping side.
Through which face of the prism does the light exit?
The bottom (hypotenuse).
The right side.
The left side.
Calculate the angle at which the ray exits the prism, relative tothe normal of that surface. Express your answer as a negativenumber if the angle is clockwise relative to the normal, and apositive number for a counterclockwise angle.
What is the maximum index of refraction for which the ray exits theprism from the right-hand side? (It may help to remember thatsin(90° - ?) = cos ?.)

A horizontal ray is normally incident on the long, hypotenuse face of a right-triangular prism. The ray extends unbent to the upper leg of the triangular prism, then reflects to move straight down. The ray is then incident on the lower leg of the triangular prism, and reflects to the left. The ray finally passes unbent through the hypotenuse of the triangular prism and extends to the left.
