   discovered by the famous astronomer Sir Frederick William Herschel. BACKGROUND: Herschel discovered the existence of infrared light by passing sunlight through a glass prism in an experiment similar to the one we describe here. As sunlight passed through the prism, it was dispersed into a rainbow of colors called a spectrum. A spectrum contains ...

   Dec 5, 2023 · William Herschel and the discovery of infrared radiation. What Is Infrared Radiation? Infrared radiation is a form of electromagnetic radiation with wavelengths in the range from about 1 micrometer (μm) to 1 millimeter (mm). This radiation, invisible to the unaided eye, has wavelengths slightly longer than those of visible light waves.

   How did William Herschel discover infra-red radiation?

   • Physics Narrative for 14-16 In 1800, William Herschel published a series of papers describing experiments which led him to identify infra-red radiation, a form of radiation beyond the red end of the spectrum of visible light. When visible light falls on a surface, some of it may be absorbed; the surface is warmed.

   Why did William Herschel create infrared light?

   • Without the filter, the intense light from the sun would burn their eyes. It was during the development of a sun filter for his telescope that William Herschel made the discovery of a form of light we now call infrared light.

   What did William Herschel discover?

   • Philosophical Transactions of the Royal Society of London, Vol. 90 (1800), pp. 255-283. William Herschel (left) is more famous today for discovering Uranus, but his experiments on the nature of light (right) led to groundbreaking insights. If something is transmitted like light, refracts like light, and disperses like light, could it be light?

   Did Herschel discover light beyond the visible range?

   • Over a short time, he would experimentally investigate the question, rapidly produce three papers, and conclude — incorrectly — that the answer was probably no. Nevertheless, Herschel was the first to discover infrared radiation and propose the existence of light beyond the visible range.
