Three waves A,B and C of frequencies 150...

Three waves A,B and C of frequencies 1500 KHz. 6MHz and 50 MHz respectively are to be transmitted from one place to another. Which of the following is the most appropriate mode of communciation?

A

A is transmitted via space wave while B and C are transmitted via sky wave

B

A is transmitted via ground wave, B via sky wave and C via space wave

C

B and C tranmitted via ground wave while A is trasnmitted via sky wave

D

B is transmitted via ground wave while A and C are transmitted via space wave

Text Solution

Verified by Experts

The correct Answer is:
B
For ground wave propagation , the frequency range is 530kHz to 1710 kHz. For sky wave propagation wave progation the frequency range is 54 MHz to 4.2 GHz. Thus option (b) is true.
