We have seen that two monochromatic light waves can interfere constructively or destructively, depending on their phase difference. One consequence of this phenomena is
A) the colors you see when white light is reflected from a soap bubble.
B) a rainbow.
C) the appearance of a mirage in the desert.
D) the way in which polarized sunglasses work.
E) the formation of an image by a converging lens, such as the lens in your eye.
