Set 16 Problem 5 A thin film of alcohol (n = 1.36) lies on a flat glass plate (n = 1.51). When monochromatic light, whose wavelength can be changed, is incident normally, the reflected light is a minimum for ) = 526 nm. As the wavelength is increased continuously, the intensity of reflected light increases until a maximum is reached for ) = 657 nm. What is the thickness t of the film? 5 t= m abc sin(x) Ox10 Submit Reset Reset All What is the condition for constructive interference at 657 nm? What is the condition for destructive interference at 526 nm
