The Fundamentals of Electromagnetic Waves
Electromagnetic waves are electric and magnetic fields traveling through free space at the speed of light; in other words, an electromagnetic wave is a propagating electromagnetic field that travels with finite velocity as a disturbance through a medium. The field itself is the disturbance, rather than simply representing a physical displacement or other effect on…

How Light Was Classified as an Electromagnetic Wave
The theory of electromagnetism was developed by physicist James Clerk Maxwell. According to his theory, an alternating current would set up fluctuating electric and magnetic fields in the region surrounding the original disturbance. Furthermore, these waves were predicted to have a frequency equal to the frequency of the current oscillations. Moreover, Maxwell theory predicted that…
