Planck-Einstein relation

An electromagnetic wave can only emit energy in quanta of

E = h ν

 


Explanation

The Planck-Einstein relation for a wave reads

E = h ν

where

    h Planck constant
    ν Frequency 

 


Alternative 1

For the angular frequency it is

E = h ω

where

    ℏ Reduced Planck constant
    ω Angular frequency
