(a) Ground wave propagation: The type of propagation in which radio waves propagate from transmitting antenna to receiving antenna following the surface of the earth is called ground wave propagation. Electromagnetic waves which are vertically polarised can travel by this mode. The intensity at the signal falls with the distance as radiowaves induce current in the ground over which they pass. As the wave propagate, the corresponding angle of tilt goes on increasing after a certain time the wave dies out. Frequency at which ground waves travel is upto 1500 KHZ. c = f.λ wavelength, λ = 200m Used for local broadcasting, ship communication etc. b) Sky wave propagation: The propagation of Radiowaves from tranmitting antenna to receiving antenna via reflection from the ionosphere is called sky wave propagation. The ionosphere region consists of ions which extends from a height of 60km to 300 km. As we go higher in the ionosphere, there is an increase in the free e...
