INTRODUCTION

Electromagnetic waves are formed when an electric field couples with a magnetic field. The magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave. The aspects of these waves are covered in the electromagnetic radiation spectrum, also called as electromagnetic radiations or electromagnetic spectra.[1] Also, Electromagnetic radiation can be described in terms of a stream of photons, which are mass less particles each travelling in a wave-like pattern and moving at the speed of light. Each photon contains a certain amount (or bundle) of energy, and all electromagnetic radiation consists of these photons. The only difference between the various types of electromagnetic radiation is the amount of energy found in the photons.
