Planck-Einstein relation

Photon energy is proportional to its frequency:

e n e r g y = (p l a n c k s c o n s t a n t) * (f r e q u e n c y)

(45)

or with common weird variables:

E = h * ν

(46)

🔗

This only makes sense if the photon exists, there is no classical analogue, because the energy of classical waves depends only on their amplitude, not frequency.
