<h2>The frequency depends upon the source energy of electromagnetic waves</h2>
Explanation:
The energy of electromagnetic wave is
E = h ν
E is the energy of source emitting the waves
here h is Plank's constant
and ν is used for the frequency of the electromagnetic wave
Thus the frequency of wave depends upon the energy of electromagnetic source . Because h is constant .
