Electromagnetic radiation, is a form of energy emitted by moving charged particles. As it travels through space it behaves like a wave, and has an oscillating electric field component and an oscillating magnetic field. These waves oscillate perpendicularly to and in phase with one another.

Electromagnetic waves and the electromagnetic spectrum - Khan …

In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. Types of EMR include radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays, all of which are part of the electromagnetic spectrum. WebIf you have an isolated point charge the field lines travel radially outwards from the charge. At some distance r from the charge the field lines are spread out over a sphere of area 4 π r 2 so the field line density, i.e the field strength, is proportional to 1/ r … lithium south development aktie forum
