Radio waves for Communication Radio waves are electromagnetic waves with wavelengths larger than the infrared light. Like all other electromagnetic waves‚ they travel at the speed of light. The wavelengths can vary from the size of a football field to the size of a football. They can be produced naturally by large stars and by lightning. Man-made radio waves are used for transmitting signals and currents. Specific Properties of Radio Frequency (RF) Current Radio frequency is the frequency of radio

Longitudinal and transverse waves Sound is transmitted through gases‚ plasma‚ and liquids as longitudinal waves‚ also called compression waves. Through solids‚ however‚ it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure‚ causing local regions of compression and rarefaction‚ while transverse waves are waves of alternating shear stress at right angle to the direction of propagation
