Which of the following modes is used for propagation of very high frequencies?

Which of the following modes is used for propagation of very high frequencies? Correct Answer Space wave propagation

Space wave propagation is defined as the radio waves that occur within 20km of the atmosphere. 

The waves which travel in a straight line between the transmitting antenna and receiving antenna are known as space wave.

The radio waves in this propagation can propagate either directly or after reflection from the ground or in the troposphere.

It is generally used for Line-of-Sight communication and satellite communication. It is mostly used for signals having a frequency in the Ultra high-frequency range(UHF).

Important Points

  • Ground Wave propagation  is a method of radio wave propagation that uses the area between the surface of the earth and the ionosphere for transmission.
  • Longitudinal waves are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of propagation of the wave.
