electromagnetic radiations are basically particles called Photons according to standard model of particles. they have energy in pure form without any mass. “ E=h*v “. energy of a photon is discrete that is they can only be in the multiples of plancks constant “h”. since h is so small our spectrum seems to be continuous. read more
Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small portion of the EM spectrum, which contains a broad range of electromagnetic wavelengths. read more
Electromagnetic radiation is composed of electrons and photons. Since electromagnetic radiation can display wave as well as particle properties, the manner in which the radiation is presenting itself, and the way it is measured, will define which component or what ratio the components are present. read more
