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? nplastic = Air Plastic Air 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!

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.
