The Vividh Bharti Station of All India Radio, Delhi, broadcasts on a frequency of 1,368 kHz (Kilohertz). Calculate the wavelength ( ) of the electromagnetic radiation emitted by transmitter. Which part of the electromagnetic spectrum does it belong to?

Options

  1. A319.4 m and X-rays
  2. B319.4 m and radiowave
  3. C219.3 m and microwave
  4. D219.3 m and radiowave

Correct answer

D. 219.3 m and radiowave

Step-by-step solution

v=1,368 10^3 ~Hz = C v = 3 10^8 ~m / s 1368 10^3 ~s ⁻¹ =219.3 ~m The range of wavelength of radiowaves is 100 m to radiation is 10000 m .
