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 = 1.3000 x 106 m/s. Relative to the center, the tangential speed is v+ = 0.5700 × 105 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 5.390 × 1014 Hz. Find the measured frequency for the light from (a) region A and (b) region B. (Give your answer to 4 significant digits. Use 2.998 × 108 m/s as the speed of light.) (a) Number i Units (b) Number i Units Galaxy Earth B
