Answer:
c = λf
E = h f
the characterization of electromagnetism is given as a function of energy or frequency.
Explanation:
In waves the frequency and donut length are related by the speed of the wave
c = λf
therefore the two quantities are not independent.
The energy of an electromagnetic wave is given by
E = h f
where h is the planck constant and f the frequency of the wave
This energy determines how the wave interacts with the surrounding medium. Low energy waves only create movement of the atomic nuclei and as the energy increases, the electrons are excited.
As a result of the above, the characterization of electromagnetism is given as a function of energy or frequency.
