- Electromagnetic energy can be termed electromagnetic radiation. It is a common term used to describe the energies associated with electromagnetic waves. It is the energy that propels such waves to propagate through any medium. Electromagnetic radiation has no charge or mass, and it moves in a pack of light energy known as photons.

This article is about the Electromagnetic energy and its uses. It explains how electromagnetic energy travels in waves, spans a broad spectrum from radio waves to gamma rays, and how NASA's scientific instruments use it to study the Earth, solar system and universe beyond. The article also mentions that our atmosphere protects us from exposure to h...
Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. When you tune your radio, watch TV, send a text message, or pop popcorn in a microwave oven, you are using electromagnetic energy. You depend on this energy every hour of every day. Without it, the world you know could not exist.
The Earth's atmosphere protects us from exposure to harmful higher-energy waves that can be ionizing and cause damage to cells in organic matter but is not helpful when studying sources of high-energy radiation in space as instruments have to be positioned above Earth's atmosphere.
NASAspacecraft provide scientists with a unique vantage point helping them "see" at higher-energy wavelengths that are blocked by the Earth's protective atmosphere while some microwaves can even pass through clouds making them best for transmitting satellite communication signals.
Energy and Momentum. Electromagnetic waves have energy and momentum that are both associated with their wavelength and frequency.
Aug 10, 2016 · An electromagnetic wave can also be described in terms of its energy—in units of measure called electron volts (eV). An electron volt is the amount of kinetic energy needed to move an electron through one volt potential.
Electromagnetic waves bring energy into a system by virtue of their electric and magnetic fields. These fields can exert forces and move charges in the system and, thus, do work on them. However, there is energy in an electromagnetic wave itself, whether it is absorbed or not.
