A charged particle oscillates about its mean equilibrium position with a frerquency of `10^9 H_z`. The electromagnetic waves produced.

Options

A. will have frequency of `10^9Hz`
B. will frequency of `2xx10^9Hz`
C. will have a wavelength of 0.3m
D. fall in the region of radiowaves

Answer

(a,c,d)

Explanation

Here, `v=10^9Hz, lambda=c//v=3xx10^8//10^9=0.3m`.
This wavelength radiation (=0.3m) or frequency radiation `10^9Hz` falls in the region of radio waves.
Thus, options (a) , (c) and (d) are correct.
