the vividh bharati station of All india Radio, Delhi , broadcasts on a frequency of 1,368 kHz (kilo hertz). Calculate the wavelength of the electromagnetic radiation emitted by transmitter . Which part of the electromagnetic spectrum does it belong to

Explanation

Given `v = 1.368 kHz = 1.368 xx 10^(3)s^(-1)`
Velocity of light, `c = 3 xx 10^(8) ms^(-1)`
Wavelength, `lambda = ?`
`lambda = (c)/(v) = (3 xx 10^(8) ms^(-1))/(1.368 xx 10^(3) s^(-1)) = 219.3 m`
The wavelegth of electromagnetic radiation emitted by transmitter is 219.3m.
This is a characteristic radio wave wavelength.
