(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 60.0⁰ if the angle of incidence is 46.0°? See figure below. Visible light Angular spread Deviation of red light G Y B V Screen R (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°?

A man shines a flashlight from a boat into the water, illuminating a rock as in the figure below. What is the angle of incidence O, (in degrees)? 2.52 m | 02 1.07 m HINT

Determine the maximum angle 0 for which the light rays incident on the end of the light pipe in the figure below are subject to total internal reflection along the walls of the pipe. Assume the light pipe has an index of refraction of 1.27 and the outside medium is air. O 2.00 μm

The light beam shown in the figure below makes an angle of = 32.4° with the normal line NN' in the linseed oil. Determine the angles and 0'. (The refractive index for linseed oil is 1.48.) 0 = 0' = Air Linseed oil Water
