(a) 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 spread (in degrees) of visible light passing through a prism of apex angle 60.0° if the angle of incidence is 53.0°? See figure below. Deviation of -red light Visible light Angular spread Screen 2.118 Your response differs from the correct answer by more than 10%. Double check your calculations. (b) What If? What is the angular spread (in degrees) of visible light passing through a prism of apex angle 60.0° if the angle of incidence is 90°?
