Concept:

An oscillating or accelerated charge is supposed to be source of an electromagnetic wave. An oscillating charge produces an oscillating electric field in space which further produces an oscillating magnetic field which in turn is a source of electric field. These oscillating electric and magnetic field, hence, keep on regenerating each other and an electromagnetic wave is produced.

The frequency of an electromagnetic wave produced by the oscillator will be same to the value of frequency of a charged particle that is oscillating about its mean position.

\(\implies\)The frequency of EM wave= Frequency of oscillating charge.

Frequency of oscillating charge=v.

So, the frequency of EM wave=v.

Hence, the correct answer is Option-2-v.
