There are many different sources of radiation that vary by intensity. . . Intro to Electro Magnetic Waves. (. or electromagnetic radiation). (or EMR). Electro-Magnetic Radiation is an interesting subject in physics in part due to the fact that we interact with EMR (electromagnetic Radiation) or technology that makes use of our understanding of electromagnetic Radiation to enhance our lives. .

The Scottish physicist James Clerk Maxwell (1831–1879) was the first person to truly understand the fundamental nature of light. . He proved in 1865 that an electromagnetic disturbance should propagate in free space with a speed equal to that of light..
