A thin soap film (n = 1.35) is suspended in air. The spectrum of light reflected from the film is missing two visible wavelengths of 490.8 nm and 589.0 nm, with no missing wavelengths between the two.
(a) What is the thickness of the soap film?
(b) what are the missing, visible wavelengths that are reflected?
(c) What wavelengths of light are strongest in the transmitted light?
