How do electromagnetic waves carry sound as electrical signals?
Wiki User
∙ 13y ago
The electromagnetic wave is "modulated" (changed) to represent the signal. For example, in AM (amplitude modulation), the strength (amplitude) of the wave is increased or decreased, according to the signal.

Electromagnetic waves do not typically carry sound as electrical signals. Sound is carried through mechanical vibrations in a medium, such as air or water. Electrical signals can be used to transmit sound information through devices like microphones and speakers, but this is distinct from the way electromagnetic waves function in transmitting information.

Is music electromagnetic?
No.
Do light waves carry electrical and magnetic energy and does sound?
Light waves carry both electrical and magnetic energy, as they are electromagnetic waves. Sound waves do not carry electrical or magnetic energy; instead, they are mechanical waves that propagate through a medium, typically air.
What is the purpose of the cone on a speaker?
The cone on a speaker is designed to move back and forth in response to electrical signals, producing sound waves that travel through the air. It helps to amplify the sound by converting the electrical signals into physical vibrations that create audible sound.
Do sound waves carry electrical and magnetic energy?
No, sound waves do not carry electrical or magnetic energy. Sound waves are vibrations of particles in a medium, such as air, that propagate as mechanical waves through that medium. They do not involve the movement of electric charges or magnetic fields.
What instrument converts electrical energy to sound or image signals in a radio or television?
The instrument that converts electrical energy to sound or image signals in a radio or television is called a speaker for sound signals and a screen or monitor for image signals. These devices receive electrical signals and convert them into audible sound waves or visual images for the viewer.

What piece of station equipment converts electrical signals to sound waves?
a speaker's 'coil' (and magnet) converts electrical signals to sound

What is sound turned into electrical signals by?
Sound is turned into electrical signals by a device called a microphone. Microphones convert sound vibrations into electrical impulses that can then be processed or recorded by various electronic devices.
What do waves carry or transfer?
Waves can carry energy and information across space. The type of wave determines what exactly is being carried - for example, sound waves carry energy that we perceive as sound, while electromagnetic waves carry energy and information in the form of light or radio signals.
What energy transformation takes place when you turn a radio?
When you turn a radio on, electrical energy from the battery is transformed into sound energy and electromagnetic waves, allowing you to hear radio signals.
How does tv transmit and detect the waves?
TV transmits and detects waves using a combination of electrical signals and electromagnetic waves. Inside a TV, signals are encoded into electromagnetic waves by the transmitter and then decoded back into images and sound by the receiver, which allows the TV to display the content on the screen. This process involves converting the electrical signals carrying the audio and video information into electromagnetic waves that travel through the air to be picked up by antennas on the TV set.
What kind of energy is involved hearing and vision?
The answer is sound or wave energy.Waves.In the form of sound and light.
How is sound transmitted and received via telegraph?
Sound is transmitted via telegraph by converting sound waves into electrical signals. These electrical signals are then sent through a telegraph wire to a receiver on the other end. The receiver converts the electrical signals back into sound waves, allowing the message to be heard.
