HW 5 Phys5405 f06 due 9/28/06 1) JDJ chapter 11 problem 20 2) JDJ chapter 11 problem 21. In part b do just the first decay. 3) JDJ chapter 11 problem 22 4) A photon of frequency f leaves the surface of a star of mass M and radius R. a)When the photon is very far from the star, it has a different frequency f’. Show that | Δ f f | = GM Rc 2 and calculate the sign of Δ f . You can assume | Δ f f | << 1 in the use of potential energy in your derivation.

Unformatted text preview: b)calculate f f for the sun and the earth. You can use R s = 6 . 965 10 8 , R e = 6 . 378 10 6 m and M s = 1 . 986 10 30 , M e = 5 . 974 10 24 kg for the radii and masses. c) The period of rotation of the sun is 24.7 d. What is the Doppler shift for 500 nm light emitted from the edge of the suns disk at the equator? Compare the magnitude of this shift with the gravitational shift. 1...
