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.

Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation electromagnetic waves What is electromagnetic radiation (EMR)? electromagnetic an electric field a magnetic field is a wave that propagates (radiates) through a vacuum at the speed of light (just under 300 000 m/s) and transfers energy from one place to another these waves carry energy as synchronized oscillations of electric and magnetic field Electromagnetic radiation can range from low to high frequency, which is measured in hertz, and can range from low to high energy, which is measured in electron volts. Wavelength, another term associated with electromagnetic radiation, is the distance from the peak of one wave to the next

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.
