Electromagnetic energy or light energy
What Is Light Energy? The sun emits an enormous amount of electromagnetic radiation (solar energy). Humans can see only a fraction of this energy, which is referred to as “visible light.” The manner in which solar energy travels can be described and measured as waves. Scientists can determine the amount of energy of a wave by measuring its wavelength, the distance between two consecutive, similar points in a series of waves, such as from crest to crest or trough to trough . Do you listen to radio ,or watch television Or use microwave oven?? All these devices make use of electromagnetic waves. Radio waves, micro waves,X rays, visible light are all examples of electromagnetic waves which differ from each other in wavelength. Electromagnetic waves are produced by the motion of electrically charged particles. These waves are also called as "electromagnetic radiation" because they radiate from electrically charged particles. They travel through space as well as through air and ot...
