The surface of a flat piece of glass is covered by a thin plastic that has thickness 180 nm. There is air above the plastic film. The refractive index of the glass is 1.40 and the refractive index of the plastic film is 1.80. Light of wavelength lambda_air in air shines at normal incidence on the plastic film. What is the largest value of lambda_air for which there will be constructive interference between the light reflected at the top and...

Problem 3 [25 pts]: White light, with a uniform intensity across the visible wavelength range of 400 nm to 720 nm, is perpendicularly incident on a glass film, of index of refraction ng = 1.52 and thickness d = 340 nm,, suspended in air. At what wavelength 2 is the light reflected by the film brightest to an observer?

In your research lab, a very thin, flat piece of glass with refractive index 2.40 and uniform thickness covers the opening of a chamber that holds a gas sample. The refractive indexes of the gases on either side of the glass are very close to unity. To determine the thickness of the glass, you shine coherent light of wavelength λ0 in vacuum at normal incidence onto the surface of the glass. When λ0= 496 nm, constructive interference occurs for 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...
