what is light?

Answer 1

Light is basically an electromagnetic wave. It's the same thing as X-rays, ultraviolet, infrared, etc. but with a different frequency. Frequency determines what an electromagnetic wave is going to be. The lowest thing possible in the electromagnetic spectrum are radio waves and the highest are gamma rays.

I hope I made it clear enough. Blessings.

Edit - in the chart I gave you "visible" is the same as light.

Answer 2

Light is electromagnetic radiation with a wavelength that is visible to the eye (visible light) or, in a technical or scientific context, electromagnetic radiation of any wavelength [citation needed]. The elementary particle that defines light is the photon. The three basic dimensions of light (i.e., all electromagnetic radiation) are:
* Intensity (or amplitude), which is related to the human perception of brightness of the light,
* Frequency (or wavelength), perceived by humans as the colour of the light, and
* Polarization (or angle of vibration), which is only weakly perceptible by humans under ordinary circumstances.

Due to the wave-particle duality of matter, light simultaneously exhibits properties of both waves and particles. The precise nature of light is one of the key questions of modern physics.

Answer 4

Light can be described as waves if you do an experiment looking for wave properties and particles if you do an experiment looking for particle properties.

If you ask waves of what? The answer might be put as waves of itself. Alternatively you could describe it as made up of photons, which are made up of alternately magnetic and electric fileds generatin each other! As on collapses in strength the other grows in strength - (I think.) For an excellent description of light you probably need to use mathematics, and forget about any physical explanations.

In simpler terms, light is called electromagnetic radiation, just like xrays, radio waves and so on. Its wavelength is appropriate to be detected by eyes.

Answer 5

the spectrum of colours it is made up of light waves that are so small it isn't visible to the naked eye

Answer 6

It may be defined as the absence of darkness.

Answer 7

A thing that sucks up dark until tonight.

Answer 8

light is that which reveals all else

Answer 9

a wave and a particle

Answer 10

illumination that destroys darkness.
