E = hv

where

E = energy,

h = Planck's constant

v = frequency.

Explanation:

Einstein proposed that electromagnetic energy was transmitted in quanta or packets. This gave rise to modern Quantum Physics.

The usual representation of a photon or energy packet is

E = hf

where f = frequency.

The frequency is related to the speed of light by

c = fλ

where

c = speed of light

λ = wavelength
