1.	Three waves A,B and C of frequencies 1600 kHz, 5 MHz and 60 MHz, respectively are to be transmitted from one place to another.Which of the following is the appropriate mode of communication?A. A is transmitted via space wave while B and C are transmitted via sky waveB. A is transmitted via ground wave, B via sky wave and C via space waveC. B and C are transmitted via ground wave while A is transmitted via sky waveD. B is transmitted via ground wave while A and C are transmitted via space wave
Answer» Correct Answer - B Mode of communication frequency range Ground wave propagation - 530 kHz to 1710 kHz Sky wave propagation - 17 kHz to 40 MHz Space wave propagation - 54MHz to 42GHz
