## Question

The Vividh Bharati station of All India Radio, Delhi broadcasts at a frequency of 1368kHz (kilohertz). Calculate the wavelength of the electromagnetic radiation emitted by the transmitter. Which part of the electromagnetic spectrum does it belong to?

### Solution

219.3 m

and *v* = 1368 kHz. (Given)

= 1368 × 10^{3} cycles s^{–1} (1 kHz = 10^{3} cycles s^{–1})

= 1368 × 10^{3} s^{–1}

It belongs to the radiowave region of the electromagnetic spectrum.
