Unformatted text preview: between momentum (a particle property) and wavelength (a wave property) p = h/ The first real experimental proof of this relationship came from Davisson and Germer in 1925, who found that electrons will diffract and interfere like waves, just like X-ray photons (light). For example, an electron with a velocity of 5.97 X 10 6 m/s (mass of an electron =9.11 X 10-28 g) has a wavelength of: So, matter and light are composed of particles that have wave-like properties. The wave-like behavior is only observed on the subatomic length scales where the masses are small enough for the wavelengths to be detectable....
