The Vividh Bharti station of All India Radio , Delhi, broadcasts on a frequency of1,368 kHz. Calculate the wavelength of the electromagnetic spectrum it belongs to
Hint `: lambda= ( c )/( v) ` `1kHz =10^(3)Hz`

Explanation

` lamda = ( C )/(V ) 1 MHz = 10 ^(3 ) Hz`
Frequency (v) `= 1368 KHz`
` = 1368 xx 10^(3) Hz (s^(-1))`
` (1KHz = 10 ^(3) Hz)`
` lamda =(c )/(v ) = ( 3.0xx10^(8) ms^(-1))/( 1368 xx 10 ^(3) S^(-1))`
`= 219 .3 m`
this belong to ratio wave wavelength .
