A 269 nm thin film with index of refraction 1.71 floats on water(with index of refraction 1.333). What is the largest wavelength ofreflected light for which constructive interference occur? Answerin units of m (for this part I got 1.84 x 10 ^-6 m)
I need help with the second part of the question: What is the2nd largest wavelength that interferes constructively? Answer inunits of m.
