If you had light of wavelength 700nm when emitted (l0=700nm), what wavelength would an observer, who is moving away from the source with a speed v=0.05c, measure for that light?
This is a question from the topic Relativity. To solve this problem, we need knowledge of Relativistic Doppler's Effect. Relativistic Doppler's Effect is applicable when the observer moves with a speed comparable with the speed of light.
Here, The given wavelength of light is a proper wavelength and we have to find the observed wavelength.
