Question

Light is incident along the normal to face AB of a glass prism of refractive index 1.62, as shown in the figure. (Figure 1)

Part B

Find αmax, the largest value the angle α can have without any light being refracted out of the prism at face AC if the prism is immersed in water (with index of refraction 1.33).

Express your answer in degrees. Ignore any reflections from the surface BC.

Find the angle ϕ between the filter's polarizing axis and the direction of polarization of light necessary to increase the ratio of the clouds' intensity to that of the blue sky so that it is three times the normal value.
