Three waves A,B and C of frequencies 1600 KHz, 5MHz and 60 MHz, respectively are to be trasnmitted from one place to another which of the following is the most appropriate mode of communication?

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
Range of frequencies is as follows:
Ground wave : `300 Hz"to" 300 kHz`
(it may go upto 3 MHz)
sky wave : `300 kHz "to" 3 MHz`
Space wave :`3 MHz "to" 300 GHz`.
