Задача id16606

A monochromatic beam falls on the vertical face of a transparent prism, whose cross section is a right triangle. The refractive angle of the prism is φ = 30°. Find the angle of deviation of the beam emerging from the prism from its original direction if the angle of incidence of the beam on the vertical wall of the prism is a = 30°, and the refractive index of the prism material is n = 1.5. Solve the problem for cases when the beam is directed: a) from bottom to top; b) from top to bottom.
