Light is a form of electromagnetic radiation (EMR). The term light usually refers to visible light, but this is not the only form of EMR. As we will see, visible light occupies a narrow band in a broad range of types of electromagnetic radiation.

Electromagnetic radiation (EMR) consists of waves. The waves contain electric and magnetic energy. The electromagnetic spectrum (EMS) includes different types of energy waves. At one end of the spectrum, there are very low energy waves. Radio waves are an example of low energy waves. At the other end of the spectrum, there are very high energy wave...
Radiation can be either non-ionizing or ionizing. 1. Non-ionizing radiation doesn’t have enough energy to ionize atoms or molecules. That means it can’t cause atoms to gain or lose electrons. There are several types of non-ionizing radiation. They include near ultraviolet light, visible light, infrared radiation, microwaves and radio waves. Even if...
Particle radiation is made up of atomic or subatomic particles. These particles include protons, neutrons and electrons. They all have kinetic energy. That’s the energy is the energy an object has when it’s in motion. Both alpha particles and beta particles produce ionizing radiation. The charge they carry can remove electrons from atoms. They can ...
Some types of radiation have enough energy that they can knock electrons out of their orbits around atoms, upsetting the electron/proton balance and giving the atom a positive charge. Electrically charged molecules and atoms are called ions .
Mar 19, 2020 · There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. The first is an alpha particle.
Apr 8, 2008 · Explainer: Understanding light and electromagnetic radiation. Here's a simple guide to the different types of electromagnetic energy that move as waves. The electromagnetic spectrum describes different types of radiation, from visible light to gamma rays and more.
Apr 10, 2022 · James Clerk Maxwell showed that whenever charged particles change their motion, as they do in every atom and molecule, they give off waves of energy. Light is one form of this electromagnetic radiation. The wavelength of light determines the color of visible radiation.
