SmartArt Examples 25. The figure below shows the situation in which light is transmitted through a thin film of thickness L 285 nm. If n 1.55, n2 1.60 and n3 1.33 what is the visible wavelength λ for...
A light ray in air (n= 1) is incident on a thin film of oil (noil = 1.60) floating on top of water (nwater = 1.33), as shown below. The wavelength of the incident light in air is Aair = 640 nm. The oil layer has a thickness t = 0.5 um. The ray is assumed to be incident practically along the normal. That is, we won't be worried about angles of reflection or refraction when doing this problem. However,...
