Planck's relation
Description
Electrons can only gain and lose energy by jumping from one allowed orbit to another, absorbing or emitting electromagnetic radiation with a frequency “f” , determined by the energy difference of the levels.
The Planck–Einstein relation,also referred to as the Einstein relation, Planck’s energy–frequency relation, is a formula integral to quantum mechanics, and states that the energy of a photon (E) is proportional to its frequency (f).
(The frequency of the radiation emitted at an orbit of period T is the reciprocal of the classical orbit period).
Variables
E2 | Initial electron energy (J) |
E1 | Final electron energy (J) |
