The waves that are used for line-of-sight (LOS) communication are
The waves that are used for line-of-sight (LOS) communication are
Show Hint
Space waves are used for LOS communication like TV and mobile signals because they travel directly through the atmosphere.
Updated On: May 12, 2025
- Sky waves
- Space waves
- Ground waves
- Sound waves
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Line-of-sight (LOS) communication requires that the transmitter and receiver be in direct view of each other without any obstacles in between.
Space waves, which include microwave and UHF radio waves, travel in straight lines and are suitable for LOS communication such as TV transmission, satellite links, and mobile phones.
Sky waves reflect off the ionosphere, and ground waves follow the curvature of the Earth, both of which are not line-of-sight.
