- A student holds a laser that emits light of wavelength 632.8 nm. The laser beam passes through a pair of slits separated by 0.300 mm, in a glass plate attached to the front of the laser. The beam then falls perpendicularly on a screen, creating an interference pattern on it. The student begins to walk directly toward the screen at 3.00 m/s. The central maximum on the screen is stationary. Find the speed of the 50th-order maxima on the screen.9. Two light waves are initially in-phase and have the same wavelength of 638 nm in air. They enter and then exit two equal length (L) parallel layers of glass with n₁ = 1.67 (layer 1) and n₂ = 1.61 (layer 2) as shown below. When the two waves exit the glass into the air, they have a phase difference of 3π/2 radians between them. Find the minimum length L for which this can occur. layer 1 layer 2 → LAn optical coating with an index of refraction of 1.23 is applied to glass with an index of refraction of 1.50. If the thickness of this coating is 184nm, what wavelength(s) of visible light in air are most strongly reflected from this surface? Visible wavelengths range from 350nm to 700nm.

- A thin layer of oil floats on a puddle of water. When sunlight hits the film from directly above, the colors red (650 nm) and violet (390 nm) are reflected. What is the minimum thickness of the oil? Use n=1.5 for the oil, and n=1.33 for water.A glass sheet measuring 15.0 cmcm ×× 29.0 cmcm is covered by a very thin opaque coating. In the middle of this sheet is a thin, straight scratch 0.00125 mmmm thick, as shown in (Figure 1). The sheet is totally immersed beneath the surface of a liquid having an index of refraction of 1.41. Monochromatic light strikes the sheet perpendicular to its surface and passes through the scratch. A screen is placed under the liquid a distance 32.0 cmcm away from the sheet and parallel to it. You observe that the first dark fringes on either side of the central bright fringe on this screen are 23.0 cmcm apart. What is the wavelength of the light in air? Express your answer in nanometers.
