Energy of a photon equation using frequency
WebPhotons always move with the speed of light. Photons are electrically neutral. Photons have no mass, but they have energy E = hf = hc/λ. Here h = 6.626*10 -34 Js is a universal constant called Planck's constant . The energy of each photon is inversely proportional to the wavelength of the associated EM wave. WebUse the Planck Equation! E = hν. Pretty simple eh? The E is the total energy in joules of a single photon with a frequency of ν (nu). Planck's constant is h and is defined as such: h = 6.626 × 10-34 J·s. Also notice that frequency ν is directly proportional to the energy. They scale with each other: if you double the frequency, you will ...
