(2 points) Optical fibers are made of glass, where light is trapped inside the fiber by total internal reflection. This example is not a fiber geometry and doesn't include the gradations in refractive index that are used, but still illustrates the point of total internal reflection. Suppose you have a piece of glass, with light incident from the glass side toward an air interface. The refractive index of the glass is 1.45. What is the critical angle where all light...

Two glass plates are separated by fine wires with diameters d1 = 0.0500 mm and d2 = 0.0520 mm, as indicated in the figure(Figure 1) . The wires are parallel and separated by a distance of 7.00 cm. If monochromatic light with λ = 569 nm is incident from above, what is the distance (in cm) between adjacent dark bands in the reflected light? (Consider interference only between light reflected from the bottom surface of the upper plate and light...

A monochromatic light ray enters a glass sphere of radius 5 cm from air as shown in the figure. The incident ray is parallel to the diameter AOB with a separation of h = 4 cm. After entering the glass sphere, the ray crosses the diameter AOB at a certain point between center O and point B.mainly ask (d) and (e)(d) If incident light is unpolarized, is the reflected light at point P perfectly polarized? If not, find another separation...

An important experimental device that uses interference is the Michelson interferometer. Michelson interferometers are used to make precise measurements of wavelengths and of very small distances. A Michelson interferometer takes monochromatic light from a single source and divides it into two waves that follow different paths. Interference occurs when the two light waves are recombined. The figure below shows the principal components of a Michelson interferometer. A ray of light from a monochromatic source A strikes the beam splitter C,...
