Q)

# A changed particle oscillates about its mean equilibrium position with a frequency of $10^9\;Hz$. What is the frequency of electromagnetic waves produced by the oscillator ?

$\begin{array}{1 1} 10^8\;Hz \\ 10^{-8}\;Hz \\ 10^9\;Hz \\ 10^{-9}\;Hz \end{array}$

Hence the frequency of the electromagnetic wave produced by the oscillator is $10^9\;Hz$
