If u read a science book you will know that light waves can be converted into electrical energy.
When you watch TV, electrical energy is being converted into light energy and sound energy. The electrical energy powers the screen, which emits light for you to see, and it also powers the speakers, which produce sound waves for you to hear.
A photodetector or light sensor is used to convert light energy into electrical signals, which can then be converted into sound using a speaker or headphones. The electrical signals are amplified and converted into sound waves that we can hear.
The answer is sound or wave energy.Waves.In the form of sound and light.
Sound energy is converted into electrical energy through a device called a microphone. When sound waves hit the microphone's diaphragm, it vibrates and changes the mechanical energy into electrical signals. These electrical signals represent the sound waves and can be amplified and recorded for playback.
In a radio, electrical energy from the batteries or outlet is converted into electromagnetic waves by the transmitter. These waves travel to the receiver where they are converted back into electrical signals, which are then converted into sound waves that we hear through the speaker.
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.
In a microphone, sound energy is converted into electrical energy. This happens when sound waves cause a diaphragm to vibrate, which in turn generates electrical signals. In headphones, electrical energy is converted back into sound energy. This process involves electrical signals being converted into vibrations by a diaphragm, which produces sound waves that we can hear.
When you use a microphone, sound energy (acoustic energy) is converted into electrical energy. The microphone captures sound waves and converts them into electrical signals that can be amplified and recorded. This electrical signal can then be transmitted or stored for playback.
In a tape recorder, electrical energy from the batteries or power source is transformed into mechanical energy to drive the motor that spins the tape reels. When recording, sound waves are converted into electrical signals (electrical energy), which are then encoded onto the magnetic tape as magnetic energy. During playback, the magnetic energy on the tape is converted back into electrical signals (electrical energy) that are amplified and converted into sound waves (sound energy) through the speakers.
An ordinary cell phone has cell batteries (of course). Chemical energy is stored in the batteries and is converted into electrical energy when needed by the phone. This energy is converted into radio waves, or electromagnetic energywhen we speak and travels to other phones. It can also be converted into light energy for display and like almost all electrical energy conversions gives out thermal (heat) energy as waste.electrical energy -------> electromagnetic energy+light energy+heat energy
In a radio, electrical energy from a power source is converted into electromagnetic energy (radio waves) by the transmitter. The radio's antenna captures these radio waves and converts them back into electrical signals, which are then converted into sound waves by the speakers, thus transforming the energy back into sound energy for us to hear.
Sound energy can be converted into electrical energy through a process called piezoelectricity. This involves using materials that generate an electric charge when they are subjected to mechanical stress, such as vibrations from sound waves. When sound waves cause these materials to vibrate, they produce an electric current that can be harnessed as electrical energy.
