Well, when you transmit something as an electromagnetic wave, it is no longer an electric current, since an electromagnetic wave doesn't involve movement of charges. However, you can convert electrical energy into an electromagnetic wave, transfer that, and then convert it back to an electric current at the receiving end.
The principle of radio waves is that change of current strength will generate waves. Advantage of this special phenomenon information can be loaded on the waves through modulation.when radio waves arriving receive side through space the change of electromagnetic field generated by waves will lead to current in conductor To extract information from change of current and reach the purpose of messaging.
I'm sorry, but they do not. The convert light waves into electricity. Heat impedes the process.
Sound waves are longitudinal waves. These would vibrate a diaphragm which has been attached with a coil kept in a magnetic field. As the coil vibrates then current is induced. This is how sound wave gets changed into electric current.
Sound is actually a series of sound waves or vibrations. These waves pulse against the eardrum, which the bones to the ear send to the brain as sounds. Acoustics in audio equipment convert sound on a record back into sound waves.
Microphones will convert sound waves into electrical signals. An ear (i..e human ear) will also convert sound waves into electrical signals.
A: For the same reason a heater is parabolic to reflect heat, For the antenna the opposite is true to focus the incoming waves
Tthe radio waves move in weird directions to create sound.
Antena Internaţional was created in 2006.
The duration of La Antena is 1.5 hours.
AM transmitters convert sound into amplitude modulated radio waves which am radios convert into electrical pulses which speakers convert into air waves that are converted into sound by our eardrum.
To convert sound waves into mechanical waves
La Antena was created on 2007-01-24.

Radio Antena Satelor was created on 1991-12-25.
Go on the Nicoclub.com site and search for power antena and there will be instructions. If your antena will not retract all of the way a piece of the plastic has broken off in the antena motor that has to be removed before you can place a new antena in it. Its easy to do.
