∙ 12y agoSound waves are not converted into radio waves. First sound waves are changed into electrical signal using a microphone. Then this mild signal is amplified. Now a high frequency radio wave is modulated with this amplified signal. This modulated radio wave is then propagated through space.

∙ 13y agoIn most devices, including headphones, earphones, radios, televisions and computers, electrical energy is transformed to sound energy by an electrodynamic loudspeaker. A speaker consists of a coil of wire suspended in a magnetic field. Changes in the current in the wire cause motion of the coil--the same principle of conversion of electrical to mechanical energy first demonstrated by Michael Faraday in 1821. The electrodynamic loudspeaker is actually a specialized form of electric motor. Like other electric motors, an electrodynamic loudspeaker can be also used in reverse--as a generator--to transform sound energy into electrical energy.

It used the electrical energy to amplify the radio signal. - that is an electromagnetic wave.

How energy is transformed in battery-operated radio?
through sound energy
What energy does an electric fan use?
In an electric fan electrical energy is transformed into mechanical energy and in loudspeaker the electrical energy is converted into sound energy.
What is an example of thermal energy being transformed into sound energy?
an example of thermal energy being transformed into sound energy is the crackling of a fire
When you plug a radio into an outlet and turn it on you hear sound What type of energy transformation is taking place?
The main energy-changes are as follows: Chemical (in the battery) to electrical Electrical to sound
When an object that is falling loose potential energy what is this transformed into?
The potential energy is transformed into kinetic energy, heat and sometimes sound.
How is energy transformed in radio?
through sound energy
How energy is transformed in battery-operated radio?
through sound energy
How energy is transformed in battery operated radio?
A radio receiver transforms electrical energy to acoustic energy
What energy does an electric fan use?
In an electric fan electrical energy is transformed into mechanical energy and in loudspeaker the electrical energy is converted into sound energy.
How is electrical energy transformed to other forms of energy?
Energy transformed by the means of energy transformation.
What energy transformation takes place when you turn a radio?
sound to electric energy

Is a radio a sound energy?
A radio produces sound, and therefore sound energy. The radio waves, however, are electromagnetic energy, not sound. The function of a radio is to convert that electromagnetic energy into sound energy.

What energy conversions occur in a radio?
In a radio you have the conversion of radio wave energy to sound wave energy.
