It was experimentally tested in 1845 by Buys Ballot in Holland, after it had been mentioned in an 1842 paper published by its namesake, who described observations of a luminous body.

Since there is no medium for the propagation of light, the effect on light is described by different formulas than that for mechanical waves, such as sound. It is often used in Mossbauer effect studies, as well as redshift, which is caused by this phenomenon. FTP, name this effect describing the perceived change in frequency of a moving object by a stationary observer, and named after the Austrian who discovered it.
