ASKYOUR TEACHER PRACTICE ANOTHER The figure below shows a right triangular prism, with an apex angle of 90. An incoming light ray, traveling in air, is incident on the left side of the prism, making an angle of incidence of 8 = 53.0. (The lower left vertex of the prism is also at the same angle, as shown.) The prism has an index of refraction of n = 1.50. The light ray reflects off a mirrored surface at the base of the prism, then exits the prism on its right side. The outgoing ray makes a refraction angle of with the normal to the right side of the prism. Calculate the angle (in degrees). Incoming ray Outgoing ray Need Help? [inssaw)] _ Submit
