Web27 de abr. de 2015 · Apr 27, 2015. According to the equation E = n ⋅ h ⋅ ν (energy = number of photons times Planck's constant times the frequency), if you divide the energy by Planck's constant, you should get photons per second. E h = n ⋅ ν → the term n ⋅ ν should have units of photons/second. Answer link. Photons obey the laws of quantum mechanics, and so their behavior has both wave-like and particle-like aspects. When a photon is detected by a measuring instrument, it is registered as a single, particulate unit. However, the probability of detecting a photon is calculated by equations that describe waves.
