Three waves \(\mathrm{A}, \mathrm{B}\) and \(\mathrm{C}\) of frequencies \(1600kHz,\,5MHz\) and \(60MHz\), respectively are to be transmitted from one place to another. Which of the following is the most appropriate mode of communication?
1 A is transmitted via space wave while B and \(\mathrm{C}\) are transmitted via sky wave
2 B is transmitted via ground wave while A and \(\mathrm{C}\) are transmitted via space wave
3 A is transmitted via ground wave, B via sky wave and \(\mathrm{C}\) via space wave
4 B and C are transmitted via ground wave while \(\mathrm{A}\) is transmitted via sky wave
Explanation:
For ground wave propagation, the frequency range is \(530\,kHz\) to \(1710\,kHz\). For sky wave propagation, the frequency range is \(1710\,kHz\) to \(40\,MHz\). For space wave propagation, the frequency range is \\(54\,MHz\) to \(4.2\,GHz\). Thus option (3) is correct.
