Question

A particular station of All India Radio, New Delhi broadcasts on a frequency of 1,368 kHz (kilohertz). The wavelength of the electromagnetic radiation emitted by the transmitter is : [speed of light $c = 3.0 	imes 10^8 	ext{ ms}^{-1}$]

Accepted Answer

Using the relation $\lambda = \frac{c}{
u}$, where $c = 3.0 	imes 10^8 	ext{ m/s}$ and $
u = 1368 	imes 10^3 	ext{ Hz}$. $\lambda = \frac{3.0 	imes 10^8}{1368 	imes 10^3} \approx 219.3 	ext{ m}$.
