10 A Distant Galaxy Is Simultaneously Rotating And Receding From The Earth As The Drawing Shows The Galactic Center I 2 (32.56 KiB) Viewed 42 times
10) 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 = 1.80 x 106 m/s. Relative to the center, the tangential speed is vt = 5.00 x 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 than the emitted frequency of 5.80 x 104 Hz. Find the measured frequency for the light from each of the following. AUG VT VI Galaxy Earth (a) region A Hz (b) region B Hz
11 ) Unpolarized light whose intensity is 1.80 W/m2 is incident on the polarizer in the figure. E cose 1 Unpolarized light Polarizer Analyzer Photocell E (90° E cose (a) What is the intensity of the light leaving the polarizer? W/m2 (b) If the analyzer is set at an angle of 0 = 78° with respect to the polarizer, what is the intensity of the light that reaches the photocell? W/m2
