Question

A thin plastic film that is d = 0.242 μm thick appears green
when viewed from directly above (i.e. normal incidence).
What is the index of refraction of the plastic film if the
wavelength of the green light is Agreen = 510 nm?

Note: The index of refraction of diamond, the
hardest substance on Earth, is 2.42, so that
of the plastic will surely be less than that!
