1. The problem statement, all variables and given/known data A soap bubble n=1.33 is floating in air. If the thickness of the bubble wall is 115 nm, what is the wavelength of the light that is most strongly reflected 2. Relevant equations 2nt=(m+0.5)(lambda) 3. The attempt at a solution most strongly reflected = constructive interference t=115 nm lambda = unknown n = 1.33 assumption m=0 plug and chug to get lambda so I got the answer, but I was confused on why we make the assumption that m=0, couldn't m technically be any integer number? Do we just automatically assume that m=0 for "most strongly reflected" if a specific desired wavelength is not given? thank you!!
