The electromagnetic spectrum includes common regimes such as ultraviolet, visible, microwave, and radio waves. He turned around einsteins equations of motion and proposed that the wavelength of a particle be given by h over p where, of course, p here is the mass times the velocity. But he turned it around and said, if you have matter with a momentum p, well, that matter ought to have a wavelength lambda.
