Vedclass · Answer

(D) Ground wave propagation is a method of radio wave propagation that uses the area between the surface of the Earth and the ionosphere for waveguide. Ground waves are typically used for low-frequency and medium-frequency communication. However,the specific range mentioned in the options refers to the wavelength range used for ground-based communication systems,which is typically between $10^{-3}\, m$ and $0.1\, m$ for specific microwave applications or line-of-sight communication.
