Detailed explanation-1: -Space wave propagation is defined for the radio waves that occur within the 20km of the atmosphere ie; troposphere, comprising of a direct and reflected waves. These waves are also known as tropospheric propagation as they can travel directly from the earth’s surface to the troposphere surface of the earth.

Detailed explanation-2: -A radiowaves that travels in a straight line from the transmitting antenna to the receiving antenna is known as space waves .

Detailed explanation-3: -Line of sight (LOS) is the imaginary line between an observer and the target. In communication, line of sight is the direct path from a transmitter to the receiver and the obstructions that may fall in that path. A clear line of sight is important to high-speed communication.

Detailed explanation-4: -The radio waves from the transmitting antenna propagate through the sky towards the receiver, either directly or by reflection from the ground, this kind of wave propagation is called skywave propagation. It is also called ionospheric wave propagation.
