A soap film is viewed in white light. If the film is much thinner than the wavelength of blue light, what is the appearance of the film? a) The soap film appears blue because all others colors are transmitted. b) The soap film appears red because all other colors are transmitted. c) The soap film appears white because it reflects all wavelengths of visible light. d) The soap film appears totally transparent because it reflects no visible light.

A soap film of index of refraction n=1.33 is 465 nm thick and lies on top of a glass plate (index of refraction 1.52). Sunlight (which we can assume is made up of all wavelengths between 380 nm to 750 nm) travels through the air and strikes the soap film perpendicularly. a. Draw a diagram indicating the rays which will interfere (reflected from the front surface of the soap and from the soap-glass interface), indicating all phase changes that occur....
