The yellow D,1 line from a sodium discharge lamp has a vacuum wavelength of 589.5923 nm. Suppose such light falls at 30.00° on the surface of a film of soybean oil (n = 1.4729) suspended (within a wire frame) in air. What minimum thickness should the film have in some region if that area is to strongly reflect the light?
