Whats the minimum thickness of a soap bubble film on which light of wavelength 500nm shines that will give distractive interference of the reflected light? Nair=1, Nsoap=1.46
Homework Answers
86 nm; first, the wavelength in the soap is w/1.46. Then, since one reflection is "hard" (180 deg phase shift) and the other is "soft" (no phase shift), the added light path through the soap (2x thickness) must be 1/2 wavelength.

A child is playing with a bubble wand, which is a large rectangular wire frame that contains a soap film. The child holds the wand vertically, which causes the film to be thinner at the top and thicker at the bottom, forming a wedge shape. Assume a thickness of essentially zero at the top. White light shines on the film with approximately normal incidence. The child views the reflected light from the film and sees the first violet interference band...

Problem 11: As the film of a soap bubble thins, it becomes darker, because the path length difference for the reflected light becomes small when compared with the wavelength of the light and there is a phase shift upon reflection at the outer surface. In this problem, assume the wavelength of visible light is in the range 400 nm to 700 nm. If a soap bubble becomes dark when the path length difference is less than one fourth the wavelength,...
