The proportionality can be replaced by an equality:

Quanta : The smallest quantity of energy that can be emitted in the form of electromagnetic radiation . Quanta and quantum of radiant energy are used synonymously. The energy of the radiation is proportional to the frequency of the emitted radiation: E.
