Schrödinger a Compton-scattering-re talált ki egy hullámmagyarázatot, de a fotoeffektusra ugyan olyan jól alkalmazható.

"Compton effect – the change of frequency and  wave vector of X-ray radiation in process of scattering on free  electron is usually considered as convincing demonstration of corpuscular aspect of electromagnetic field.

 However Schrödinger has shown, that this effect can be completely explained by wave theory, without  any necessity to enter the idea of corpuscular  photon."
