Derive doppler shift equation
WebThe equation is often seen in the form: fO = fS/ (1 − vS/c) Change in frequency The change in frequency or Doppler frequency shift is: Δf = fS − fO Note that when the source is moving toward the observer, fS > fO and Δf is negative. Substitute for fO: Δf = fS − fSc/ (c − vS) Factor out fS: Δf = fS[1 − c/ (c − vS)] Simplify: WebFractional Wavelength Change. For purposes of determining recession speed of stars and galaxies with the Doppler effect by observation of the red shift of spectral lines, it is convenient to express the Doppler effect …
