Propagation of waves the process of communication involves the transmission of information from one location to another as we have seen, modulation is used to encode the information onto a carrier wave, and may involve analog or digital methods. Ground wave propagation: when signals travel via the ground wave they are modified by the ground or terrain over which they travel they also tend to follow the earth's curvature signals heard on the medium wave band during the day use this form of propagation.

The propagation of an electromagnetic wave, which has been generated by a discharging capacitor or an oscillating molecular dipole, is illustrated by figure 1 the spark current oscillates at a frequency (n), which is a characteristic of the circuit. The way waves propagate varies, because there are two types of waves: transverse and longitudinal transverse waves vibrate at 90 degrees to the direction of propagation the wave might be moving forward, but transverse waves vibrate side to side. Line-of-sight propagation above 30 mhz neither ground nor sky wave propagation operates transmitting and receiving antennas must be within line of sight.
