A soap bubble (n = 1.34) floating in air has the shape of a spherical shell with a wall thickness of 121 nm. (a) What is the wavelength of the visible light that is most strongly reflected? nm (b) Explain how a bubble of different thickness could also strongly reflect light of this same wavelength. This answer has not been graded yet. (c) Find the two smallest film thicknesses larger than 121 nm that can produce strongly reflected light of the same wavelength. (Enter your answers from smallest to largest.) nm nm
