(frequency) = (speed of light)/(wavelength)
Einstein's physics. Axiom: Constant speed of light. Consequence: Any frequency shift is caused by an inversely proportional wavelength shift. Obvious nonsense.
Einstein-free physics. Axiom: Constant wavelength of light. Consequence: Any frequency shift is caused by a proportional speed-of-light shift. At least in this case
