I've got a somewhat simple question, and I think its from me overlooking something stupid...but how does using doppler shift work if in any moving rest frame the speed of light is supposed to stay at 3(10^8) m/s? I know that E=hc/λ, so for the wavelength of the light λ to change, the only thing that could change is the energy right? So does moving towards or away from a light source change the energy of the photons coming at you, but only in your frame of reference?
