Problem 5: 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, what is the thickest the soap film can be and appear dark at all visible wavelengths? Give your answer in nanometers.

Ideal Gas Law

Ideal gas law states that the product of pressure and volume of a gas directly varies with the product of the number of moles, the universal gas constant, and the temperature of the gas.
