A photoacoustic cell can turn sound energy into light energy. This device uses sound waves to generate acoustic vibrations, which in turn create light emissions due to the excitation of a phosphor material. This phenomenon is known as sonoluminescence.
A microphone is a device that converts sound energy into electrical energy. Sound waves cause a diaphragm in the microphone to move, which then generates an electrical signal that represents the sound.
When a TV turns on, electrical energy is converted into light (in the form of the screen's display) and sound energy (from the speakers). Some energy is also dissipated as heat due to the TV's components.
An electric bulb, like an incandescent or LED bulb, can turn electric energy into heat and light energy. An electric motor can transform electric energy into motion energy.
When you turn on a television, the electrical energy from the outlet is converted into light and sound energy by the components inside the TV, such as the screen and speakers. This energy transformation allows you to see images and hear sound on the screen.
A light bulb can be considered an output device as it converts electrical energy into light energy. In the context of a system, the light bulb would typically be connected to an input device such as a switch or sensor that controls when the light bulb turns on or off. Therefore, while the light bulb itself is an output, its operation is often dependent on input signals.
A microphone is a device that converts sound energy into electrical energy. Sound waves cause a diaphragm in the microphone to move, which then generates an electrical signal that represents the sound.
light, sound and some heat energy
When a TV turns on, electrical energy is converted into light (in the form of the screen's display) and sound energy (from the speakers). Some energy is also dissipated as heat due to the TV's components.
Firecrackers produce three types of energy: sound, light and intensity. That flourishing sound you hear after the blast is from the fast arrival of energy, which makes the air grow quicker than the speed of sound, causing a shockwave.
A battery is a device that turns chemical energy into electrical energy by using chemical reactions to generate a flow of electrons.
Heat and pressure
An electric bulb, like an incandescent or LED bulb, can turn electric energy into heat and light energy. An electric motor can transform electric energy into motion energy.

When you turn on a television, the electrical energy from the outlet is converted into light and sound energy by the components inside the TV, such as the screen and speakers. This energy transformation allows you to see images and hear sound on the screen.
A device that turns chemical energy into electrical energy is called a battery. Batteries store and release electrical energy through chemical reactions happening inside them.
One example is an electric motor, which turns electrical energy into kinetic energy.
