Electromagnetic (EM) wave also known as Electromagnetic Radiation is a self-propagating wave energy that travels at the speed of light in the form oscillating electric and magnetic fields perpendicular to each other. Electromagnetic Wave is generated when electric particles are accelerated though matter which generates electromagnetic radiation. Electromagnetic waves can travel through vacuum. Accelerating electric charge…

Energy
Energy is defined as the ability to do work. It is measured in Joule (J) named after PhysicistJames Prescott Joule who discovered the relationship between mechanical energy and heat energy which led to “Law Of Conversation” which states that energy cannot be created nor destroyed but can be converted from one form to another. Energy…
