A constant called Planck's constant directly connects the energy of a photon to the frequency of vibration of a charged particle.
E=hv 1.48 x 10-15 J
= (6.626 x 10-34) (v)
v= 1.48 x 10-15 J/6.626 x 10-34
v= 2.23 x 10 18 Hz
In physics, frequency is the number of waves that pass a fixed point in a unit of time as well as the number of cycles .
In science and engineering, frequency is a crucial metric for describing the temporal rate of change seen in oscillatory and periodic processes.
