The difference is that LEDs use less electricity.
The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.
-- fireflies -- campfire -- stars -- match -- compact fluorescent light
A mirror is not a source of light, natural or otherwise.
No, all planetary bodies only reflect light. Light is only generated by stars. This does not count artificial light or volanic light.
No, a bonfire is not considered an artificial light; it is a natural source of light created by burning wood or other combustible materials. The flames produce light through a chemical reaction, which is a natural phenomenon. Artificial light, on the other hand, refers to light produced by human-made sources like lamps, bulbs, or LEDs.
Non-luminous sources of light do not produce their own light but reflect or scatter light from other sources. Examples include the moon, planets, and objects like books or walls that reflect light from other sources like the sun or artificial lighting.
A primary light source is one that actually produces light, such as a light bulb or the sun. A secondary light source in one that ONLY reflects the light produced by a primary light source. It doesn't produce light itself, such as a mirror or the moon.
The source of light energy is typically the sun, which emits light through a process called nuclear fusion in its core. Other sources of light energy include artificial sources such as light bulbs and fire.
No, light can exist in both darkness and in the presence of other light sources. Light is a form of electromagnetic radiation that is produced by sources such as the sun or artificial light bulbs, and can be present in various environments.
Foil paper appears shiny in the dark because it reflects the light from other sources, such as ambient light or artificial light nearby. It does not produce its own light.
Our primary source of light is the sun, which emits energy in the form of electromagnetic radiation. This radiation includes visible light that illuminates our surroundings and enables us to see. Other sources of light include artificial sources such as light bulbs, fires, and electronic devices.
Light can be obtained from various sources. One common source is the Sun, which produces natural light. Artificial light can be obtained from light bulbs, lamps, LED lights, or any other device that emits light.
