When light strikes a thin film some of it transmits and some of it reflects To determine whether destructive interference occurs between light rays reflected from the top and bottom surfaces of the film first you need to determine the phase reversal status of both rays If they are O in phase then you need to change status by ensuring the path difference is a half number multiple of the wavelength out of phase then you need to maintain status by ensuring the path difference is a half number multiple of the wavelength out of phase then you need to change status by ensuring the path difference is a whole number multiple of the wavelength O in phase then you need to maintain status by ensuring the path difference is a half number multiple of the wavelength
