jcsd you just saved my ass. It was kind of you to help so much. Thank you very, very much!

Yea, I got that far.. it seems I'm having a brainfart with the 'simple algebra'. EDIT: working on it with your hint EDIT2: bleh. something's just not clicking. 5.79*10^7 is pretty close to .19c, is that telling me anything?

I calculated lambda prime/lambda to be 1.1938. How am I to solve with two of the same variable :o No matter what equation I use, it seems I keep getting an answer of 5.79*10^7.. which is pretty unrealistic seeming (and also incorrect).

Thanks for the reply Err.. are both velocities in the doppler shift equation equivalent or are they different? IE. would one of the velocities be zero because the receiving planet does not move?

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...
