The source of the light is the source of the energy carried by the light.
The heat of a fire, the chemical energy in the tail of a firefly, the kinetic
energy of the flint scraping across the stone, the heat of the filament
in the light bulb, the electricity that powers the LED or the laser, etc.

∙ 14y agoThe source of energy in this case is in whatever produced the light. Quite often the light originates from the heat of an object. This heat, in turn, may have its origin in something else, for example, the chemical energy that fuels a fire. In the case of a light bulb, the source of energy is the electricity that keeps it glowing, but once again this is indirect; for example, in an incandescent light bulb, the electricity first turns into heat.

Light is a wave that carries energy a light source emits a countless number of?
Light waves are electromagnetic waves that carry energy. A light source emits a vast number of these waves in all directions, allowing us to see objects by reflecting or refracting these waves. The energy of the light waves is what enables us to perceive the world around us through vision.
do flashlights use electromagnetic waves when creating light?
No, flashlights do not use electromagnetic waves to create light. Instead, they use electrical energy to power a light source, such as a bulb or LED, which emits visible light when energized. Electromagnetic waves are a form of energy that can transmit light, but they are not the source of light production in a flashlight.
What is an example for waves transfer energy not matter?
An example of waves transferring energy without transferring matter is light waves. Light waves can travel through a vacuum in space and transfer energy from the source (such as the sun) to the Earth without transferring any physical particles.
What type of waves mkove energy forward but the source moves up and down?
Transverse waves move energy forward while the source moves up and down. This type of wave consists of oscillations perpendicular to the direction of energy transfer. Examples of transverse waves include electromagnetic waves and light waves.
Is light a moving stream of energy?
Yes, light is a form of electromagnetic energy that travels in waves. It behaves like a moving stream of energy as it carries energy from its source to its surroundings.

Are waves a source of energy?
waves is not a source of energy

Where do light waves originate?
Light waves originate from a light source, such as the sun, a light bulb, or a laser. When an object absorbs energy, it can emit photons, which are the elementary particles of light that travel as electromagnetic waves.

Do light waves transfer energy?
Do light waves transfer energy
Why does the beam deflection decrease as length of beam decreases?
As you bring the source of light closer to the deflector the energy of the loss of energy from the light waves decreases. So the light waves strikes the deflector with greater energy. So more energy is needed to deflect them. Hence the deflection decreases.
Do light waves carry energy?
Light waves do carry energy, and when oscillated light can carry information.
How spherical waves are produce?
Spherical waves are produced when a disturbance originates from a point source and propagates uniformly in all directions, creating a wavefront that expands spherically. This can occur in various natural phenomena such as sound waves spreading from a sound source or light waves radiating from a point light source. The energy in spherical waves diminishes as the wavefront expands, resulting in a decrease in intensity with increasing distance from the source.
What happens to energy when the frequency of light waves increase?
When the frequency of light waves increases, the energy of the light also increases. This is because energy and frequency are directly proportional in electromagnetic waves, such as light. Therefore, higher frequency light waves carry more energy than lower frequency light waves.
