Created by StemPy LabA thin soap film in air is lit from the front. When it is much thinner than the wavelength of light, how does it look in reflected light?

← The molecules of a clear gas are far smaller than the wavelength of light, and they scatter light in proportion to 1/λ⁴. Compare two colours. How many times as strongly is light of wavelength 530 nm scattered, as light of wavelength 700 nm?A slip of clear plastic with refractive index 1.7 and a thickness of 1.4 µm is stuck over one of the two slits of a double-slit set-up. The set-up is lit by blue light of wavelength 460 nm. By how many fringe widths does the whole pattern slide? →
