Problem 88

Suppose you put on two pairs of polarizing sunglasses with their axes at an angle of $$15.0^{\circ}$$. How much longer will it take the light 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.
