Mirror M1 in Figure 25.15 is displaced a distance ΔL. During this displacement, 250 fringe shifts are counted. The light being used has a wavelength of 632.8 nm. Calculate the displacement ΔL.
Optical fibers are a central part of technology for rapid information transmission with a high
level of efficiency. A new type of optical fiber is crafted with an index of refraction n =
less than that of water in the vicinity of room temperature, where NH2O
fact that n < nH20 potentially problematic if the fiber should be submerged?

O A. Total internal reflection would be frustrated, allowing loss of signal.
O B. Internal reflection would actually be enhanced, so there is no problem.
C. Electric eels might have free internet access.
Assume that a material is composed of 3 layers in descending order: air (nair = 1.00), water (nwater = 1.33),
and glass (nglass= 1.52). Then, assume that a monochromatic light ray in the air passes through the surface
of water with an angle of incidence 0₁ = 40 degrees.
A. Find the angle of refraction in glass after it passes completely through the water layer.
B. Find how fast is the light ray moving in the glass?
