Rebecca Slater LO #9 2. A substance that is normally clear and colorless can appear to give off an array of colors when it is found in a very thin layer Thin films between two media often produce interference patterns: areas of destructive and constructive interference for different wavelengths. When light is involved, the result is often beautifully coloured patterns. Here we explain how these interference patterns and iridescence arise, particularly with reference to soap films.

Light that is 31 Jul 2004 Thin Film Interference Occurred in the Colloidal Films. Like the oil films floating on water showing iridescent colors due to thin film interference, we based on “ultra-thin-film interference”, including the concepts of loss-induced ( a) Thin film with thickness ℎ and complex refractive index 2, with light wedge film interference soap film wedge demonstration; Thin film interference; thin film diagram.

Thin film interference occurs between the light reflected from the top and bottom surfaces of a film. In addition to the path length difference, there can be a phase change. When light reflects from a medium having an index of refraction greater than that of the medium in which it is traveling, a \(180^{\circ}\) phase change (or a \(\lambda /2\) shift) occurs. Interference – Phase Shift What can introduce a phase shift?

It is simply something beautiful to appreciate. That notion is so wrong.
Thin films, such as the oil slick in the photo to the right, can often produce a rainbow of colors. To get this effect, the material thickness must be on the order of the wavelength of visible light, around 380 - 750 nanometers.
