The energy an electromagnetic wave transports per unit time per unit area is the intensity
An electromagnetic Wave is defined as the waves that propagate through the continuous and simultaneous oscillation of electric and magnetic fields which are perpendicular to each other. The most common examples of electromagnetic waves include X-rays, gamma rays, ultraviolet, infrared, light, radio waves, microwaves, and infrared rays
Energy, which is observable in the execution of labor as well as in the form of heat and light, is defined as the ability to do work. Energy is a preserved resource; according to the law of conservation of energy, energy can only be transformed from one form to another and cannot be created or destroyed.
