A laser beam strikes one end of a slab of material, as in the figure below. The index of refraction of the slab is 1.50. Determine the number of internal reflections of the beam before it emerges from the opposite end of the slab. (Enter an integer for the total number of complete reflections. Assume 0 = 46.2°.) 148 complete internal reflections 0 42.0 cm T 3.10 mm

The index of refraction for violet light in silica flint glass is 1.66 and that for red light is 1.62. What is the angular dispersion of visible light passing through an equilateral prism of apex angle 60.0° if the angle of incidence is 56.0°? (See figure. The index of refraction for air is 1.00.) 1.94 Your response differs from the correct answer by more than 10%. Double check your calculations.º Visible light Angular spread Deviation of red light B Screen
