A thin film of cooking oil (?=1.43) is spread on a puddle of water (?=1.33). What is the minimum thickness ?min of the oil that will strongly reflect blue light having a wavelength in air of 481 nm, at normal incidence?
?min = nm
What are the next three thicknesses that will also strongly reflect blue light of the same wavelength, at normal incidence?

A thin film of gasoline floats on a puddle of water at a gas station. Sunlight falls on the film and reflects to your eyes. You see yellow because blue (wavelength 469 nm in vacuum) undergoes destructive interference. The index of refraction for gas is 1.40 and for water is 1.33. (a) What is the wavelength of the blue light inside the gasoline? (b) What is the minimum thickness of the film?

A thin film of oil (n. =1.50) with varying thickness floats on water (nw = 1.33). When it is illuminated from above by white light, the reflected colors are as shown in the figure below. In air, the wavelength of yellow light is 580 nm. (a) What is the oil's thickness t at point B? (hint: this is the second thinnest region for yellow light]. (b) Estimate (no calculation) the oil's thickness at point A. [hint : use the result...
