The energy quantum proposed by Planck is the basis of today's quantum mechanics. De Broglie also linked this energy quantum to the energy of matter and showed that matter is a wave.In the energy body theory, I linked the energy quantum to the kinetic energy of an electron and discovered that kinetic energy is a photon. 1) The radiation interval of photons which are plane waves becomes the wavelength of light emission line spectrum, 2) When electrons and protons interact, distortion (negative energy) occurs in the foot of each rotating wave, which works a restoring force, 3) It also generates a wave (positive energy) in the corresponding space, 4) The electron (or proton) moves while being dragged by this kinetic energy, and 5) The Schrödinger equation defines the wave that combines the distortion of the foot of the electron and the wave generated in space.It is also estimated that when an electron is on the orbit of an excited proton, the wavelengths of the de Broglie waves of the electron and the proton are the same length. Then, by dividing the distance at the speed of light (3 × 10 to the power of 8) by the wavelength, and multiplying the frequency by the Planck constant, we obtain the energy quantum. It has become clear that this relationship appears as the similarity of a triangle created by the distortion of the foot of a proton. E=hν
