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 = velocity of E.M. R in vaccum
`=3 xx 10^(8) m sec^(-1)`
`v = "frequency" = 1368 kHz`
`=1368 xx 10^(3) sec^(-1)`
`= (3.00 xx 10^(8) ms^(-1))/(1368 xx 10^(3) s^(-1))`
`= 219.3 m`
This is a characteristic radiowave wavelength.
