Definition

product of the Planck constant and frequency, expressed by

Q_{p} = h ν

where $h$ is the Planck constant (ISO 80000-1) and $ν$ is the frequency (ISO 80000-3: Space and time) of the corresponding electromagnetic wave

Notes

Photon energy can be emitted, transferred or received.

For monochromatic radiation, photon energy may be expressed by photon number (photon number).

The corresponding radiometric quantity is "radiant energy" (radiant energy <electromagnetism>). The corresponding photometric quantity is "luminous energy" (luminous energy).

L'énergie photonique peut être émise, transportée ou reçue.

Pour un rayonnement monochromatique, l'énergie photonique peut être exprimée par le nombre de photons (photon number).

La grandeur radiométrique correspondante est l'«énergie rayonnante» (radiant energy <electromagnetism>). La grandeur photométrique correspondante est la «quantité de lumière» (luminous energy).
