    Light with a wavelength of 520 nm in air shines on a soap bubble (n = 1.3), resulting in thin film interference. The current thickness of the bubble is such that the interference is constructive – light reflecting from the outer surface of the bubble and light reflecting from the inner surface interfere constructively. How much would the thickness of the bubble need to be increased in order to observe destructive interference?

    Monochromatic light of wavelength 560 nm strikes a thin layer of soap, which has an index of refraction of 1.4 and rests on a bathroom tile. (a) If the layer of soap is 700 nm thick, does constructive interference, destructive interference, or partial interference occur when the light strikes the surface close to the normal? (b) What is the minimum thickness of soap that would result in no (or minimal) reflection from the surface? (100 nm)
