Answer :

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

Who defines frequency?

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 .

What is the purpose of frequency?

In science and engineering, frequency is a crucial metric for describing the temporal rate of change seen in oscillatory and periodic processes.
