Thin-film interference occurs when light hits a thin layer of material, such as a coating or a film, and is partially reflected and partially transmitted. The reflected light waves interact with each other, creating an interference pattern that depends on the thickness of the film, the wavelength of the light, and the refractive indices of the materials involved. This interference pattern gives rise to the colors and patterns we observe in thin-film interference. Essential Macleod Crack
