Photon energy meaning
WebAug 15, 2024 · 18. The equation E=nhv is used to find the energy of the photon. Energy can also be released or absorbed in small discrete packages that mean energy is quantized. Each package is termed ”quantum”. Einstein expanded on this theory with Planck’s to show that radiant energy is also quantized and the quantum of radiant energy is called a photon. Photon energy is the energy carried by a single photon. The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's … See more An FM radio station transmitting at 100 MHz emits photons with an energy of about 4.1357 × 10 eV. This minuscule amount of energy is approximately 8 × 10 times the electron's mass (via mass-energy equivalence). See more • Photon • Electromagnetic radiation • Electromagnetic spectrum See more
