For example, the splendid varieties of color found in soap bubbles, in oil films drifting on puddles of water, and in the colors of a peacock"s tail, are because of interference of this sort. Assume that an extremely dainty film of air is caught between two bits of glass, as displayed in. The eye shines these two equal light pillars at one spot on the retina. The two beams of light produce either disastrous or constructive interference depending upon whether their way distinction is equivalent to an odd or a much number of half-wavelengths respectively. Let t be the thickness of the air film. The distinction in way lengths between the two light beams displayed in the figure is obviously.
