ZBT1 Task 1: Wave Physics Ian Trimble Student ID: 000352590 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 …show more content…

Otherwise their static. No one believed Maxwell, and Hertz set out to prove Maxwell right. Hertz used two rods to serve as a receivers. When the applied a spark to one of the rods, he could get it to jump to the other rod. Hertz discovered how to make the electric and magnetic fields separate themselves and travel freely. ("The origins of radio, n.d." ) 1895 – X-rays were discovered accidentally by physicist Wilhelm Conrad Rontgen. Rontgen was working on a experiment and testing whether cathode rays could pass through glass. He noticed that a nearby tube emitted fluorescent glow of crystals. The air in the tube was released, high voltage applied, the same tube emitted a fluorescent glow. When Rontgen covered the tube in a heavy black paper, a green light could be seen. He concluded that a new light ray was being broadcast. Rontgen discovered that the light was very powerful and the same ray could pass through human tissue, but not through bones and metal objects. Medical applications were soon to follow. ("History of radiography," ) 1900 – Gamma-rays were first observed when French chemist Paul Villard was investigating radium radiation. Villard observed that a photographic sheet was affected by radioactive materials when it was shielded by lead and iron. The radiation showed no magnetic deflection. The term gamma ray was coned from Ernest Rutherford several years later in 1903. Gamma-rays are
