beam of white light is shined at normal incidence onto the outside of a soap bubble (index of soap solution = 1.340). An observer looking at the bubble, opposite to the direction of the beam, notices that green light (Lambda = 555.0 nm) is particularly bright in the reflected spectrum. What is the second thinnest wall thickness of the bubble
