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.

An early method of measuring the speed of light makes use of a rotating slotted wheel. A beam of light passes through a slot at the outside edge of the wheel, as in the figure, travels to a distant mirror, and returns to the wheel just in time to pass through the next slot in the wheel. One such slotted wheel has a radius of 3.23 cm and 130 slots at its edge. Measurements taken when the mirror is L- 1090 m from the wheel indicate a speed of light of 3.00 x 105 km/s. (a) What is the (constant) angular speed of the wheel? (b) What is the linear speed of a point on the edge of the wheel?

Roque is flying a kite along the dolomite sand of Manila Bay. If the string is 45 meters, determine the rate at which the angle of elevation is changing if the horizontal distance from him to the point directly below the kite is 13 meters. Assume that he is running at a rate of 1.2 m/s; the kite is not swaying as it flies upward; and he started from rest when the kite is directly along his field of vision.

When the sun is either rising or setting and appears to be just on the horizon, it is in fact below the horizon. 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. How does this compare to the angular radius of the sun, which is about one quarter of a degree? (In actuality a light ray from the sun bends gradually, not abruptly, since the density and refractive index of the…
