A very thin sheet of glass is 4,000nm thick. If I shine laser light of wavelength 488.0nm on it, it takes 22.0 femtoseconds ( that is 22.0·10-15s ) to pass through. What is the wavelength of the light in this sheet?

An extremely thin sheet of glass is being inspected at the factory. Illuminated by white light at near-normal incidence, the film-like sheet is 0.397 µm thick and has air on both sides. If the glass has a refractive index of 1.52, what wavelength of visible light (in nm) does it reflect most strongly? (The wavelengths of visible light range from 400 to 700 nm.)

In a physics lab, light with wavelength 486 nm travels in air from a laser to a photocell in 17.0 ns. When a slab of glass 0.850 m thick is placed in the light beam, with the beam incident along the normal to the parallel faces of the slab, it takes the light 21.3 ns to travel from the laser to the photocell. What is the wavelength of the light in the glass?    nm

Light strikes a 5.0-cm thick sheet of glass at an angle of incidence in air of 50° measured from the normal. The sheet has parallel faces and the glass has an index of refraction 1.60. (a) At what angle does the light leave the first boundary air-glass boundary? (b) After traveling through the glass the light re-emerges into the air. What is the final angle of refraction in air? (c) Draw a diagram showing the path that the light takes...

A laser produces light with a wavelength of 490 nm in vacuum. It takes 2.85 ns for the light to pass through 45 cm of an unknown transparent material. a. What is the index of refraction of the material? b. What is the wavelength of the light in the substance? c. How long would it take for this light to pass through 45 cm of water?

When I shine a red laser pointer (wavelength 650nm) on two slits, I find that what should be the central bright spot is actually a dark spot. Upon further investigation, I discover that there's a thin layer of oil covering one of the slits. The oil has an index of refraction of 1.4. What is the minimum thickness of the oil that would cause the observed effect?

White light is shone on a very thin layer of glass (n = 1.5), and above the glass layer, interference maxima for two wavelengths (and no other in between) are seen: one green wavelength of 550 nm, and one orange wavelength of 610 nm. What is the thickness of the glass layer? 1862 nm 1859 nm 1860 nm 1861 nm

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...
