• Covered are topic such as wavelength, frequency, nature and propagation of radio waves; ground and sky waves; skip distance; and fading.
• Because of the differing heights of refraction, or apparent reflection, the radio waves hit the earth surface at different points hence generating the skip distance.
• A skip distance is a distance on the Earth's surface between the two points where radio waves from a transmitter, refracted downwards by different layers of the ionosphere, fall.
