De broglie wavelength formula kinetic energy
WebJan 30, 2024 · De Broglie Wavelength In 1924, Louis de Broglie used Einstein's equation E=mc2 and incorporated it with Planck's equation. This brought together the relationship of the mass of a photon and speed of light with the photon energy. Einstein's equation: E=mc 2 m=mass of photon c=speed of light COMBINED WITH Planck's equation: E=hv WebJun 5, 2024 · This example problem demonstrates how to find the wavelength of a moving electron using de Broglie's equation.. While an electron has properties of a particle, the de Broglie equation may be used to describe its wave properties.
