Vedclass · Answer

(D) An oscillating charged particle produces electromagnetic waves of the same frequency as the oscillation frequency.Given frequency $f = 10^9 \ Hz$.Therefore,the frequency of the electromagnetic waves produced is $10^9 \ Hz$.The wavelength $\lambda$ is given by the formula $\lambda = \frac{c}{f}$,where $c = 3 	imes 10^8 \ m/s$ is the speed of light.$\lambda = \frac{3 	imes 10^8 \ m/s}{10^9 \ Hz} = 0.3 \ m$.Electromagnetic waves with a frequency of $10^9 \ Hz$ (or $1 \ GHz$) fall within the microwave region,which is a part of the radio wave spectrum.
