Question

Quizplus · Accepted Answer

The wavelengths of matter waves are determined by the de Broglie equation, which shows that their wavelength is inversely proportional to their momentum. Since matter has mass, its momentum is typically much smaller than the momentum of a photon of light. Therefore, the wavelengths of matter waves are relatively small compared to the wavelengths of visible light.
