An electric charge oscillating harmonically with frequency $750 \mathrm{kHz}$ produces electromagnetic waves of frequency
(Speed of light in vacuum is $3 \times 10^8 \mathrm{~ms}^{-1}$ )
$250 \mathrm{kHz}$
$500 \mathrm{kHz}$
$750 \mathrm{kHz}$
$1000 \mathrm{kHz}$
Solution
An electric charge oscillating harmonically with frequency $750 \mathrm{KHz}$ produces the same electromagnetic waves of frequency $750 \mathrm{KHz}$.
