Assertion: Space waves are used for litre -of -sight communication.
Reason: Space wave travels in a straight line from transmitting antenna to the receiving antenna.

Text Solution

Verified by Experts

The correct Answer is:
A
A space travels in a straight line from transmitting antenna to the receiving antenna. Space wave are used for line-of-sight communication as well as satellite comunication As frequencies above 40 MHz communication is essentially limited t line-of-sight paths.
