Explanation:
Detailed explanation-1: -What Does Radio Propagation Mean? Radio propagation is the way radio signals are transmitted from one point to another inside the earth’s atmosphere or free space. Since these are electromagnetic waves, they exhibit properties such as reflection, refraction, diffraction, absorption, polarization and scattering.
Detailed explanation-2: -Space wave propagation mode is used for the transmission of VHF and UHF because UHF and VHF can neither be propagated through Ground waves (due to high absorption in the atmosphere) nor via Sky waves (due to non reflection of the ionosphere).
