In a vacuum photons of lower energy

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).
