The iPad is a liquid crystal display backlit with light emitting diodes.
No, bells are not a light source. Bells are objects that produce sound when struck or shaken. They do not emit light.
how does a television produce sound and picture
A TeleVision because to produce an image, it needs to have some light shining from the back of the screen, therefore emitting light and it has speakers on it to produce sound all from electricity.
Heat and light. Sometimes sound, too.
thermal light and sound
A television produces light and sound energy. The electrical energy from the power source is converted into these forms of energy to display images and produce sound for viewers to see and hear.
The energy that produces light and sound in a firecracker comes from the rapid combustion of chemicals inside the firecracker. During this combustion process, the release of energy generates heat, light, and sound, creating the explosive effects seen and heard when a firecracker is ignited.
No, lasers do not produce sound. They emit light which can be used in various applications, but they do not generate any audible noise.
Mute. :)
No, light energy cannot directly make sound. Sound is produced by the vibration of particles in a medium, while light travels as electromagnetic waves. However, light energy can be converted into other forms of energy that could produce sound indirectly.
Sound requires a medium, such as air or water, to propagate. Light, on the other hand, travels as electromagnetic waves and does not require a medium. Therefore, light does not produce sound waves that can be heard by the human ear.
