1.	The vividh bharati station of All India Radio, Delhi broadcasts on a frequency of 1.368 kHz. Calculate the wave length of the electromagnetic radiation emitted by the transmitter. Which part of the electromagnetic spectrum does it belong ?
Answer» Solution :GIVEN `V=1.368kHz=1.368xx10^(3)s^(-1)` `"Velocity of light, c "= 3xx10^(8) ms^(-1)` Wavelength, `lambda=?` `lambda=(c)/(v)=(3xx10^(8)ms^(-1))/(1.368xx10^(3)s^(-1))=219.3m` The wavelength of electromagnetic RADIATION emitted by TRANSMITTER is 219.3 m. This is a characteristic radio wave wavelength.
