SUMMARY

The frequency of an electromagnetic (EM) wave is directly determined by the energy of the wave, specifically through the transition of electrons between energy levels. When an electron transitions from a higher energy level to a lower one, the energy lost is emitted as a photon, which defines the frequency of the resulting wave. This relationship is mathematically expressed by the equation E=hf, where E is energy, h is Planck's constant, and f is frequency. Thus, the frequency of a wave is intrinsically linked to the energy difference associated with electron transitions.

Hello to all,

the space around us is filled with EM waves vibrating at different frequencies...

my question is ; How does a given wave acquire it's frequency ?

The frequency of an electro-magnetic wave is determined by its energy. When an electron jumps from a higher energy level to a lower energy level, the lost energy goes into a photon. It is that difference in energy levels that determines the frequency.
 
Through the relation e=hf. Given a certain amount of energy due to be released (say by an electron changing state) the resultant wave will simply have that frequency.
