In the most extreme case, you can turn the wave on and off completely; this is commonly used in Ethernet for example. You can also modulate some aspect of the wave, such as amplitude (amplitude modulation), frequency (frequency modulation) or phase (phase modulation).Let's consider turning the wave signal on and off. The simplest way to transfer information this way is to agree to send (for example) one bit every second; in that case, if the signal is ON during one second, that might represent a "1", and if the signal is OFF during some other second, that might represent a "0".
In practice, much more than one bit per second is usually transmitted (for example, 100 million bits every second is typical, nowadays, for home Ethernet); and more complicated systems are generally used to encode the signal.
Light waves
sound energy can be transmitted from gases,plasma andliquids and as longitudinal waves, also called a compression waves. it requires a medium to propagate. through solids it can be transmitted as both longitudnal waves and transverse waves
light waves
Sound waves are transmitted in this manner.
there waves that tell sound
Analog signals are transmitted as electrical waves.
Information is usually transmitted in terms of either radio waves or acoustic energy in a telephone. Machines such as the fax are usually used.
Radio waves. Information is transmitted to & from the computer to the wi-fi connection digitally, by radio waves.
only 96% of information is transmitted and the other 4% is lost
By carrier pigeon, a runner, the mail service, electric wires, electromagnetic waves, sound waves.
S-waves are not transmitted through the outer core.
Radio waves are generated and modulated with the transmitted information at the transmitting station and radiated by its antenna. These radio waves are picked up by the receiver antenna, filtered from all the other transmitted signals, detected and demodulated by the receiver to recover the transmitted information.
The different behaviors exibited by transmitted seismic waves.
Cell phone transmission occurs using radio waves from cell towers set up in the area. Information is transmitted from one tower to the next until it reaches its destination.

Sound is transmitted through gases, plasma, and liquids as longitudinal waves. However, through solids it can be transmitted through either longitudinal waves or transversal waves. To view the source and more information go to: http://en.wikipedia.org/wiki/Sound
