Examples of Electromagnetic Waves
Gamma ray is produced during nuclear fusion reaction We all are surrounded by electromagnetic waves. Every day we are using them knowingly or unknowingly to make our life easier. In this article, we extensively discuss some examples of electromagnetic waves. But, before that, we should understand what electromagnetic waves are. Electromagnetic waves or EM waves are particular groups of transverse waves which are generated due to the simultaneous vibration of the electric and magnetic field. Magnetic field and electric field vibrate in planes perpendicular to the direction of the propagation of the wave. In the diagram below, the propagation of the wave is along the z-direction. Electric field (shown in blue) vibrates in the XZ plane and magnetic field (shown in red) vibrates in the YZ plane. Unlike sound wave and mechanical waves, electromagnetic waves do not require a medium to travel from one place to another. Moreover, all the electromagnetic waves travel at a c...
