Photon intensity equation
WebThis is the property associated with the brightness, or intensity, of the wave. ... This relationship is given by the following equation: c = ... Planck’s discoveries paved the way for the discovery of the photon. A photon is the … 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). Very-high-energy gamma rays have photon energies of 100 GeV to over 1 PeV (10 to 10 electronvolts) or 16 nanojoules to 160 microjoules. This corresponds to frequencies of 2.42 × 1…
