It is found that when light traveling in water is incident on the surface of a plastic block, Brewster’s angle is . Find the refractive index of the plastic. Use a value of 1.33 for the refractive index of water.
Light reflected at from a window is completely polarized. What is the window’s refractive index?
Suppose you put on two pairs of polarizing sunglasses with their transmission axes at an angle of relative to each other. How much longer will it take sunlight to deposit a given amount of energy in your eye compared with a single pair of sunglasses? Assume the lenses are clear except for their polarizing characteristics.
