Ground Wave …

Ground Wave is the radio waves that travel directly from the transmitting antenna to the receiving antenna near the surface of the Earth and the propagation is termed as Ground Wave Propagation or Surface Wave Propagation. The Ground Waves cannot bend round the curvature of Earth. Also Ground Wave transmission is found to become weaker for higher frequencies (i.e., lower wavelengths) of radio waves. Therefor, the Ground Wave transmission is useful with radio waves of wavelength 200 m or above. This range of the radio waves is Called Medium Wave Band.
