Electromagnetic wave theory This theory was put forward by James clark Maxwell in 1864. The main points of this theory are: 1)The energy is emitted from any source continuously in the form of radiations and is called the radiant energy. 2)The radiations consist of electric and magnetic fields oscillating perpendicular to each other and both perpendicular to the … [Read more...] about Electromagnetic Wave Theory
