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

`lambda = (c)/(v)` where `c = 3 xx 10^(8) m sec^(-1)`
`v =` frequency `= 1368 kHz = 1368 xx 10^(3) sec^(-1)`
`lambda = (c)/(v) = (3.00 xx 10^(8) ms^(-1))/(1368 xx 10^(3)s^(-1)) = 219.3m`
This is a characteristic radiowave wavelength.
