Formula: Photon Energy Per Mole
Photons with different frequency

Photon energy per mole

Photon energy per mole indicates the energy of \( 6 \cdot 10^{23} \) photons. This amount of photons makes up one mole.


Frequency of the used light. The greater the frequency, the greater the energy of one mole of photons.

Avogadro constant

The Avogadro constant is a physical constant with the value \( N_{\text A} ~=~ 6 \cdot 10^{23} \, \frac{1}{\mathrm{mol}} \) and represents the number of photons that are in one mole.

Planck's Constant

Planck's constant \( h \) is a physical constant from quantum mechanics and has the following exact value: $$ h ~=~ 6.626 \, 070 \, 15 ~\cdot~ 10^{-34} \, \mathrm{Js} $$
