Question

Red light is incident in air on a 30 degree - 60 degree - 90 degree prism as shown. The incident beam is directed at an angle of phi_1 = 46.3 degree with respect to the horizontal and enters the prism at a height h = 14 cm above the base. The beam leaves the prism to the air at a distance d = 35.5 along the base as shown. What is phi_2, the angle the beam in the prism makes with the horizontal axis? What is n, the index of refraction of the prism for red light? What is phi_3, the angle the transmitted beam makes with the horizontal axis? What is phi_1, max the maximum value of phi_1 for which the incident beam experiences total internal reflection at the horizontal face of the prism? The red beam is now replaced by a violet beam that is incident at the same angle phi_1 and same height h. The prism has an index of refraction n_violet = 1.66 for violet light. Compare d_violet, the exit distance for violet light, to d, the exit distance for red light. d_violet < d d_violet = d d_violet > d Suppose now that the violet beam is incident at height h, but makes an angle phi_1, v = 60 degree with the horizontal. What is phi_3, v, the angle the transmitted beam makes with the horizontal axis?
