A thin film having an index of refraction of 1.50 is surroundedby air. It is illuminated normally by white light. Analysis of thereflected light shows that the wavelengths 360, 450, and 600 nm arethe only missing wavelengths in the visible portion of thespectrum. That is, for those wavelengths, there is destructiveinterference.
(a) What is the thickness of the film?
nm
(b) What wavelengths in the visible portion of the spectrum arebrightest in the reflected interference pattern? (Enter youranswers from smallest to largest.)
(c) If this film were resting on glass that has an index ofrefraction of 1.60, what wavelengths in the visible spectrum wouldbe missing from the reflected light? (Enter your answers fromsmallest to largest.)
