Have you ever wondered how different appliances that we use daily work? The physics behind it? Usually, it happens as a result of electromagnetic waves. Everyday life is pervaded by artificially made electromagnetic radiation; food is heated in microwave ovens, airplanes are guided by radar waves, television sets receive electromagnetic waves transmitted by broadcasting stations, and infrared waves from heaters provide warmth. But what is this electromagnetic wave? Electromagnetic waves are transverse waves. That means the electric and magnetic fields change (oscillate) in a plane that is perpendicular to the direction of propagation of the wave. To know more on this, check out the ppt!
