Hey all. I've got a physics question due tonight (Friday) at 11pm CST and I'm stumped. Any input at all would be helpful, thanks!
A hydrogen atom, when vigorously perturbed, can emit light with a frequency of 6.16·10^14 Hz. When the same light from hydrogen atoms in a distant galaxy is observed on earth, the frequency is 5.16·10^14 Hz. Calculate the speed at which the galaxy is receding from the Earth (in units of the speed of light, c).
Cheers.
