What is the difference between visible light and electromagnetic radiation?

Answer 1

Light, electricity, and magnetism are manifestations of the same thing called electromagnetic radiation. The energy you see coming out of the computer screen you are using to read this page is made of fluctuating electric and magnetic energy fields. The electric and magnetic fields oscillate at right angles to each other and the combined wave moves in a direction perpendicular to both of the electric and magnetic field oscillations. This energy also comes in many forms that are not detectable with our eyes such as infrared (IR), radio, X-rays, ultraviolet (UV), and gamma rays. Visible light is just apart of the electromagnetic radiations. I don't think there is a difference.

Answer 2

Solar radiation (UV-A, UV-B and UV-c) is a part of electromagnetic radiation. Electromagnetic radiation means that the electrons jumps from shell to shell of the atom. When it sinks to a lower electon lever /shell, energy ia releasend. This can come in the shape of solar radiation.

Answer 3

Solar radiation comes from "our" star - the Sun.

Almost all other radiation which reaches earth comes from other "suns" - the stars, whether great or small.

A small amount of radiation is left over from the Big Bang - and is known as "Cosmic microwave background radiation".

Answer 4

Solar radiation comes from the sun, and its wavelengths are much shorter than that coming from the Earth simply because the sun is much, much hotter. Its wavelengths are centered in the visible part of the spectrum, though it also emits infrared and UV radiation.

Terrestrial radiation is entirely infrared, which is a longer wavelength than visible. There are some simple relationships that are useful to remember: All objects with a temperature emit radiation (the only objects at absolute zero are in outer space). The hotter an object, the shorter the wavelength it emits its radiation. Finally, the shorter the wavelength, the more energy it has. That's why we become concerned with being exposed to higher frequency radiation such as UV and especially x-rays.
