sun
Daylight, sunlight and skylight or all natural sources of light.
Yes, natural sources of laser light have been observed in certain animals, such as the spitting cobra, which can emit laser-like beams of red or green light from its eyes. These animals use this light for communication or hunting purposes.
artificial====================Answer #2:Fire is not light at all. But if a fire happens to be hot enoughto emit some light, then that light is perfectly natural.
Fireworks are manmade.
The radiation that a laser emits ... whether it's visible light, infrared, or microwave, has all the same physical characteristics as electromagnetic radiation from other sources has, including speed.
Daylight, sunlight and skylight or all natural sources of light.
Trillions or more. Not to mention all the lights on our small planet, the universe contains billions of stars, and they're all emitting light.
no
Unfiltered light is called white light, which contains all the visible wavelengths of light in the electromagnetic spectrum. It is typically produced by the sun or natural sources, and appears colorless to the human eye.
The sun, light bulbs, candles, and LED lights are all sources of light energy.
They are all energy sources.
No, not all light sources have the same spectra as white light. White light contains all the colors of the spectrum, while other light sources may emit only specific colors or wavelengths, resulting in a different spectral composition.
Yes , cause it has it's own light

Flash, strobe, spotlights and photofloods are all sources of Artificial Light.
To determine the total brightness of multiple light sources when their lumens are additive, you simply add up the lumens of each individual light source. This will give you the total brightness of all the light sources combined.
