In your research lab, a very thin, flat piece of glass with refractive index 2.10 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 that is reflected at the two surfaces of the glass. You find that the next shorter wavelength in vacuum for which there is constructive interference is 386 nm. (A)Express your answer with the appropriate units (B)Express your answer with the appropriate units

Two identical horizontal sheets of glass have a thin film of air of thickness t between them. The glass has refractive index 1.40. The thickness t of the air layer can be varied. Light with wavelength λ in air is at normal incidence onto the top of the air film. There is constructive interference between the light reflected at the top and bottom surfaces of the air film when its thickness is 700 nm. For the same wavelength of light...

A thin piece of glass with an index of refraction of n2 = 1.50 is placed on top of a medium that has an index of refraction n3 = 2.00, as shown in the figure. A beam of light traveling in air (n1 = 1.00) shines perpendicularly down on the glass. The beam contains light of only two colors, blue light with a certain wavelength and orange light with a certain wavelength. a) The blue light has a wavelength in...

A film of oil lies on wet pavement. The refractive index of the oil exceeds that of the water. The film has the minimum nonzero thickness such that it appears dark due to destructive interference when viewed in visible light with wavelength 673 nm in vacuum. Assuming that the visible spectrum extends from 380 to 750 nm, what is the longest visible wavelength (in vacuum) for which the film will appear bright due to constructive interference? please help thank you

23) Light of wavelength λ strikes a pane of glass of thickness T and refractive index n, as shown in the figure below. Part of the beam is reflected off the upper surface of the glass, and part is transmitted and then reflected off the lower surface of the glass. Constructive interference between these two beams will occur if

An anti-glaring uniform thin film of magnesium fluoride (MgF2, index of refraction 1.38) covers a crown glass case of refractive index 1.52. This film has a thickness such that it cancels normally incident light of wavelength 525 nm that strikes the film surface from air. The film is thicker than the minimum thickness to achieve this cancellation. Over time, the MgF2 film wears away at a rate of 2.10 nm per year. What is the minimum number of years before...

You are standing in air and are looking at a flat piece of glass (n = 1.52) on which there is a layer of transparent plastic (n = 1.61). Light whose wavelength is 512 nm in vacuum is incident nearly perpendicularly on the coated glass and reflects into your eyes. The layer of plastic looks dark. Find the two smallest possible nonzero values for the thickness of the layer. smaller value: nm larger value: nm
