So wot is light exactly? PLease good descriptions.
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[1]. In my own words: pretty much it is everything we see. If our eyes were different, we might only be able to see infared or ultraviolet rays.
Light is the energy that you see that comes from moving photons. Photons are ultra teeny tiny eensy weensy subatomic particles with no intrinsic mass. (i do not know what intrinsic means). Whenever they move, they generate energy, which is given off in the form of light which we see.
Light is made up of particles called photons. These particles can also be thought of as waves. These waves travel at certain frequencies, and these frequencies determine the color (ie. low frequency is red light, high frequency is violet light). Lower frequency than red light gives us infrared light. Higher frequency than violet light gives us ultraviolet light. All these frequencies are electromagnetic waves. (electric waves and magnetic waves travelling together)
