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 space

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
Mode of communication depends upon the frequency range. (b) is the correct choice.
The frequency (A) of 1600 Hz is transmitted via ground wave, B(v= Hz) is transmitted via sky wave and C (v=60 MHz) is transmitted via space wave.
