A distant galaxy is simultaneously rotating and receding from the earth. As the drawing shows, the galactic center is receding from the earth at a relative speed of ug = 2.30 x 106 m/s. Relative to the center, the tangential speed is VT = 0.310 x 106 m/s for locations A and B, which are equidistant from the center. When the frequencies of the light coming from regions A and B are measured on earth, they are not the same and each is different from the emitted frequency of 9.296 x 1014 Hz.

A certain type of laser emits light that has a frequency of 5.0 × 1014 Hz. The light, however, occurs as a series of short pulses, each lasting for a time of 2.9 × 1011s. (a) How many wavelengths are there in one pulse? (b) The light enters a pool of water. The frequency of the light remains the same, but the speed of the light slows down to 2.3x 10% m/s. How many wavelengths are there now in one pulse?

An isotropic point source emits light at wavelength 470 nm, at the rate of 210 W. A light detector is positioned 450 m from the source. What is the maximum rate dB/dt at which the magnetic component of the light changes with time at the detector's location? The speed of light is c = 3 x 108 m/s, and Ho = 47 x 107 H/m. Number 2.98754 UnitsTT/s the tolerance is +/-5%

how would you solve this? Light is emitted from the light source, reflects from mirror surface X to the plane mirror, and then to the position of surface Z. By the time the light moves from the X to Z position, mirror surface X will have moved to the position of mirror surface Z. The light then continues to the observer. The distances from the light source and the observer to the rotating mirrors are negligible. The distance from the rotating mirrors to the plane mirror is 35.0 km.If the mirrors are rotating at 480 rev/s, the speed of light calculated from the given information is     a 7.44  10–9 m/s b 1.34  108 m/s c 2.98  10–8 m/s d 3.36  107 m/s

Two antennas located at points A and B are broadcasting radio waves of frequency 104.0 MHz. The signals start in phase with each other. The two antennas are separated by a distance d = 8.7 m. An observer is located at point P on the x axis, a distance x = 110.0 m from antenna A. The points A, P, and B form a right triangle. Now observer P walks along the x axis toward antenna A. What is P's distance from A when they first observe fully constructive interference between the two waves?
