White light in air (n = 1.00) shines on an oil film of thickness
t that floats on water. The oil has an index of refraction of 1.50,
while the refractive index of water is 1.33. When looking straight
down at the film, the reflected light looks orange, because the
film thickness is just right to produce completely constructive
interference for a wavelength in air of 600 nm (orange light). What
is the minimum possible thickness of the film?
