An antenna converts electromagnetic waves, such as radio or microwave frequencies, into electrical currents by inducing voltage across its length as the waves interact with its conductive elements. This induced voltage generates an alternating current in the antenna that can be captured and processed by electronic circuits to extract information or power. The design of the antenna, including its length and shape, determines its efficiency at converting waves into current.

How do radiowaves work?
Radio waves are a type of electromagnetic radiation that transmit information through the air by vibrating at a specific frequency. Radio transmitters convert electrical signals into radio waves, which are then transmitted through antennas. Receivers pick up these radio waves and convert them back into electrical signals for playback through speakers.
What device is used to convert sound to electricity?
A microphone is typically used to convert sound waves into electrical signals. The microphone's diaphragm vibrates in response to sound waves, which causes a coil of wire to move within a magnetic field, generating an electrical current proportional to the sound waves.
What is the effect of current on waves?
An electric current can induce electromagnetic waves when it flows through a conductor. This can result in the generation of radio waves, microwaves, or light waves depending on the frequency and intensity of the current. The relationship between current and waves is described by Maxwell's equations in electromagnetism.
Can you convert transverse to longitudinal?
No, it is not possible to convert transverse waves into longitudinal waves, as they are fundamentally different types of waves. Transverse waves oscillate perpendicular to the direction of wave propagation, while longitudinal waves oscillate parallel to the direction of wave propagation.
Is it possible to transmit electricity as electromagnetic waves?
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.
What device converts sound waves to electric current?
Microphones will convert sound waves into electrical signals. An ear (i..e human ear) will also convert sound waves into electrical signals.
Why antena is in parabolic form?
A: For the same reason a heater is parabolic to reflect heat, For the antenna the opposite is true to focus the incoming waves
How a radio can capture the radio signal?
Tthe radio waves move in weird directions to create sound.

What do am radios convert sound into?
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.
What do ears convert?
Sound waves.
When was Radio Antena Satelor created?
Radio Antena Satelor was created on 1991-12-25.
