A soap film (n 1.33) is 375 nm thick and coats a flat
Chapter 27, Problem 27.36(choose chapter or problem)
A soap film (n 1.33) is 375 nm thick and coats a flat piece of glass (n 1.52). Thus, air is on one side of the film and glass is on the other side, as Figure 27.42 illustrates. Sunlight, whose wavelengths (in vacuum) extend from 380 to 750 nm, travels through the air and strikes the film nearly perpendicularly. For which wavelength(s) in this range does constructive interference cause the film to look bright in reflected light? C
