WebLight is a form of electromagnetic wave. The amplitude and frequency of both mechanical and electromagnetic waves affect how we experience them. A light wave’s amplitude … WebBasically, gasoline forms a thick layer on top of water, so light is reflected once when it passes from air to gasoline, and another time when it passes from gasoline to water. When those two waves interfere constructively, you get different wavelengths/colors, and because the gasoline has different thickness across, you get all sorts of colors. the pim project
