Question

What is space wave propagation ? State its three components.

Answer 1

When the radio waves from the transmitting antenna propagate along the space surrounding the earth to reach the receiving antenna, either

directly or after reflection from ground or in troposphere, the wave propagation is called Space wave propagation.

The space wave has three components:

(a) Direct wave : Along path, radio waves reach receiving antenna directly.

(b) Ground reflected wave: The radio waves reach the receiving antenna after reflection from ground.

(c)Tropospheric wave: The radio waves reach the receiving antenna after reflection from

troposphere.
