Introduction
We benefit greatly the benefits of long distance communication, eating food from different parts of the countries without fear of spoilage, radiation treatment, and heating up food in a matter of minutes, and a myriad of other wonders all do the wonders of waves, be they sound waves as well as light waves. In this timeline, we will look at all of the different light waves, their history, and their benefits.
Annotated Timeline
1800 – William Herschell was a contemporary of Sir Isaac Newton and was fascinated with one of Newton’s recent discoveries. Newton posited that when light was refracted through a prism, different colors of the visible light spectrum were visible. Herschel hypothesized that each one of the colors contained a different temperature. When he measured each separate color, he discovered that each one had a different temperature. Herschell also discovered that the temperatures increased from the violet to the red part of the color spectrum. He also discovered that when he went above the red spectrum, a color not visible to the human eye, that the temperature increased. This led to the discovery of infrared light. (“History of infrared”, n.d., para 1)
1801 – Jumping on the coat tails of Herschell’s groundbreaking discoveries, a year later Johann Wilhelm Ritter, a polish born physicist, hypothesized that light might exist past the infrared spectrum. Ritter discovered that if he used silver chloride, and the same glass prism, that an intense reaction would occur in the silver chloride. These discoveries were beyond the red of the spectrum. The color that had these intense reactions were violet, hence the term ultraviolet. ("History of ultraviolet," 2014)
1887 – Heinrich Hertz, a German physicists conducted many experiments based on James Clerk Maxwell’s theory that electrical fields and magnetic fields can bond together to form electromagnetic waves. Maxwell
