A thin film appears to be green when viewed from above (λ = 550 nm). The thin film has an index of refraction n = 1.2, and lies on top of a liquid with n = 1.33. Above the thin film is air, with n = 1. What is the smallest possible (non-zero) thickness of the film?

A scientist notices that an oil slick floating on water when viewed from above has many different rainbow colors reflecting off the surface. She aims a spectrometer at a particular spot and measures the wavelength to be 750 nm (in air). The index of refraction of water is 1.33.Part A: The index of refraction of the oil is 1.20. What is the minimum thickness of the oil slick at that spot? t= 313nmPart B: Suppose the oil had an index...

A thin soap film (n = 1.33) is supported in air. The film gives a bright fringe when viewed at normal incidence in reflected light with λ = 550 nm. Which of the following might be the thickness of the film?

The reflection of light from the thin film of thickness t as
shown in the figure appears violet (400nm) when viewed from above.
This means the two rays reflecting off of the two surfaces
interfere constructively. t is the minimum thickness. The dark grey
material has a higher index of refraction than the light grey with
the white being air. For what minimum thickness relative to t would
it need to be for the film to now appear red (700nm)...

Problem 8: Consider a thin film of of soapy water (11-1.33) on Plexiglas. Since light is a wave, there are many thicknesses of this film that will result in constructive interference. Part (a) What is the smallest non-zero thicknesses, in nanometers of this film if it appears green (constructively reflecting 550 nm light) when illuminated perpendicularly by white light?

A thin piece of glass with an index of refraction of n=1.50 is placed on top of a medium that has an index of refraction n=2.0. A beam of light traveling in air (n=1.0) shines perpendicularly down on the glass. The beam contains light of only two colors, blue light with a wavelength of 450 nm and orange light with a wavelength of 600 nm. What is the minimum non-zero thickness of the glass that gives completely constructive interference for...
