visible White light reflected at perpendicular incidence from a soap film suspended in air has, in the spectrum, a constructive interference at A = 600 nm and a destructive interference at λ = 450 mm, with no other maxima or minima in between. If the refractive index of the film is n = 1.33, what is the film thickness?
