Textbook Question
Chapter 31, Problem 23P
What is the minimum angular speed at which Michelson’s eight-sided mirror would have had to rotate to reflect light into an observer’s eye by succeeding mirror faces (1/8 of a revolution, Fig. 31-14)?

If Michelson had used a six-sided mirror to measure the speed of light and obtained an image when the mirror was rotating 4.88 x 10^4 RPM, what would be the calculated speed of light if the fixed mirror was placed 30 km from the rotating mirror?
109 In Fig. 34-54, a fish watcher at
point P watches a fish through a
glass wall of a fish tank. The watcher
is level with the fish; the index of re-
fraction of the glass is 8/5, and that Watcher
of the water is 4/3. The distances are
di = 8.0 cm, dz = 3.0 cm, and dz =
6.8 cm. (a) To the fish, how far away
does the watcher appear to be?
(Hint: The watcher is the object.
Light from that object passes
through the wall's outside surface, which acts as a refracting sur-
face. Find the image produced by that surface. Then treat that im-
age as an object whose light passes through the wall's inside sur-
face, which acts as another refracting surface.) (b) To the watcher,
how far away does the fish appear to be?

The explanation for this seeming paradox is that light from the sun bends slightly when entering the earth’s atmosphere, as shown in Fig. Since our perception is based on the idea that light travels in straight lines, we perceive the light to be coming from an apparent position that is an angle d above the sun’s true position. (a) Make the simplifying assumptions that the atmosphere has uniform density, and hence uniform index of refraction n, and extends to a height h above the earth’s surface, at which point it abruptly stops. Show that the angle d is given by as attached. where R = 6378 km is the radius of the earth. (b) Calculate d using n = 1.0003 and h = 20 km.

- A fiber optic gyroscope is a fascinating device used to measure rotation rate (angular velocity), which is a necessary parameter to be measured in through autonomous navigation systems (inertial navigation). They are based on an interferometer conceived in 1913 by the French physicist Georges Sagnac. In a Sagnac interferometer, a beam of light is split and the two beams are made to follow the same path but in opposite directions. On return to the point of entry the two light beams are allowed to exit the fiber loop (see Figure and undergo interference. If the loop rotates clockwise, the clockwise optical path becomes longer than the counterclockwise optical path (see Figure 2). The phase difference (interference) is proportional to the rotation rate (angular velocity). Derive this relationship for a fiber optic gyroscope that uses a 1 km long fiber aranged in a 25 cm spool and a laser beam with wavelength of 1.5 um.
