What is space wave propagation ? Give two examples of communication system which use space wave mode.
A TV tower is 80 m tall. Calculate the maximum distance upto which the signal transmitted from the tower can be received.

Text Solution

Verified by Experts

When wave travel in space in a straight line from the transmitting antenna to the receiving antenna, this mode of proagation is called the space wave propagation.
Examples : Television broadcast, microwave links, satellite communication.
`d= sqrt(2hR) = sqrt( 2 xx 80 xx 6.4 xx 10^(6)) = 32 km`
