A proof of its validity was offered by A.W. Simon and independently by Bothe and Geiger and dubbed the coincidence method. The original experiment observing it made use of molybdenum K-alpha radiation that was run through a block of carbon and the resultant angles were measured with a Bragg spectrometer. Most scientists were skeptical of Einstein's description of light until the discovery of this phenomenon. FTP, name this effect defined as the shift in wavelength upon scattering of light from stationary electrons.
