English: The relativistic Doppler shift formula is applicable to both sound and light. This spacetime diagram illustrates a source (tuning fork) and receiver. Two vibrations of the tuning fork at O and A. The signal propagates with speed equal to the magnitude of the worldline AB, and the proper duration of the pulse equals the magnitude of OB.
The word "dopplergraph" is a combination of the words doppler and photograph. Dopplergraphs are two-dimensional records of variations in the doppler shift in light intensity. Dopplergraphs do not need to be a record of the shift of visible light, but of any radiated wave, which includes electromagnetic waves and acoustic waves. [1]

At radio frequencies the amount of bending cannot be measured directly; instead, the bending can be calculated using the Doppler shift of the signal given the geometry of the emitter and receiver. The amount of bending can be related to the refractive index by using an Abel transform on the formula relating bending angle to refractivity.
