An electric charge oscillating harmonically with frequency $750 \mathrm{kHz}$ produces electromagnetic waves of frequency (Speed of light in vacuum is $3 \times 10^8 \mathrm{~ms}^{-1}$ )
  1. $250 \mathrm{kHz}$
  2. $500 \mathrm{kHz}$
  3. $750 \mathrm{kHz}$
  4. $1000 \mathrm{kHz}$

Solution

An electric charge oscillating harmonically with frequency $750 \mathrm{KHz}$ produces the same electromagnetic waves of frequency $750 \mathrm{KHz}$.
