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 = 1.6 × 106 m/s. Relative to the center, the tangential speed is vT = 0.4 × 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 6.200 × 1014Hz. find the measured frequency for the light from
(a) Region A and
(b) RegionB.
