Pre-Lab Assignment (1 point) A horizontal light ray initially in air (n1: 1) approaches a prism as shown in the diagram below. The prism is in the shape ofa right triangle and has an index of refraction of 1.5 (Le. in: 1.5). a. Draw the trajectory of the light ray to show how it enters and exits the prism. b. Calculate the angle (with respect to the normal) at which it both enters and exits the prism. Show your work
