The rhinestones in costume jewelry are glass with index of refraction 1.50. To make them more reflective, they are often coated with a layer of silicon monoxide of index of refraction 2.00. What is the minimum coating thickness needed to ensure that light of wavelength 539 nm and of perpendicular incidence will be reflected from the two surfaces of the coating with fully constructive interference?

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...

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...

You want to coat a pane of glass that has an index of refraction of 1.54 with a 195-nm-thick layer of material that has an index of refraction greater than that of the glass. The purpose of the coating is to cancel light reflected off the top of the film having a wavelength (in air) of 540 nm. The coating material is very expensive, so you want to use the thinnest possible layer. 1) What should be the index of...

A sheet of glass has an index of refraction 1.50. Assume that the index of refraction for air is 1.00. a.) Light is incident on the glass sheet, at an angle of incidence of 60 degrees. Sketch the path the light takes as it refracts at each of the two parallel surfaces. Calculate and label the size of each angle in degrees, including angles of incidence and refraction at each of the two parallel surfaces shown. b.) Calculate the velocity...
