It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.All of these waves form part of the electromagnetic spectrum Electromagnetic radiation is a form of energy that is present all around us and takes various forms like microwaves, television waves, radio waves, gamma rays, X-rays, etc. In this piece of article, we will discuss electromagnetic radiation and its properties. What is Electromagnetic Radiation
What Is Electromagnetic Radiation? There are electric fields that develop through variances in voltage, and there are magnetic fields that develop from the flow of electric current. The higher the electric field or the greater the magnetic field, the stronger the electromagnetic radiation People rely on these technological tools for work, communicating with friends and family, school, and personal enjoyment. What most people don't seem to realize, however, is that all of these electronic devices are known to emit waves of Electromagnetic Radiation (EMF) Radiation exists across what's called the electromagnetic spectrum. This radiation ranges from very high-energy (called high-frequency) on one end of the spectrum, to very low-energy (or low. Electromagnetic radiation is a form of energy. The light that we see is a type of electromagnetic radiation. However it is only a very small part of the entire electromagnetic spectrum. Sound, another form of energy, is not part of this spectrum Radiation — energy moving in the form of particles or waves. Familiar radiations are heat, light, radio waves, and microwaves.

Electromagnetic Radiation Electromagnetic radiation is a type of energy that is commonly known as light.Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 10 8 meters per second through a vacuum. We call this the speed of light; nothing can move faster than the speed of light Electromagnetic radiation is reflected or absorbed mainly by several gases in the Earth's atmosphere, among the most important being water vapor, carbon dioxide, and ozone. Some radiation, such as visible light, largely passes (is transmitted) through the atmosphere Electromagnetic (EM) radiation is a form of energy propagated through free space or through a material medium in the form of electromagnetic waves. EM radiation is so-named because it has electric and magnetic fields that simultaneously oscillate in planes mutually perpendicular to each other and to the direction of propagation through space. 9. Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced. Depending on the kind of atom and the amount of energy, this electromagnetic radiation can take the form.

Electromagnetic radiation exists in the form of particles called photons. Each particle or photon is an extremely small grain of energy-- an energy packet-- so to speak. When we think of minute particles we might think of dust or sand. But these particles are solid, molecular substances Electromagnetic radiation is the messen-ger, or the signal from sender to receiver. The sender could be a TV station, a star, or the burner on a stove. The receiver could be a TV set, an eye, or an X-ray film. In each case, the sender gives off or reflects some kind of electromagnetic radiation. All these different kinds of electromagnetic.
