William Herschel and the discovery of 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.
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.
Infrared radiation was discovered by William Herschel in 1800. He was studying the heating effect of different colours of light by using a prism to produce a spectrum of colours and thermometers to measure their heating effect. He noticed that the heating effect got stronger as he went from the blue end of the spectrum to the red.
2 de ago. de 2013 · What Herschel had discovered was a form of light (or radiation) beyond red light, now known as infrared radiation. Herschel's experiment was important because it marked the first time that someone demonstrated that there were types of light that we cannot see with our eyes.

Infrared light was discovered about 200 years ago by the German-born British astronomer William Herschel. About one half of the starlight produced and emitted throughout the history of the Universe has been absorbed and re-emitted as infrared light.
He deduced the presence of invisible 'calorific' rays, now called 'infrared' radiation, and provided the reason for naming ESA's infrared space observatory after him. During the rest of his life, Herschel produced lists of thousands of nebulae and star clusters, and he was the first to distinguish between distant clusters and dusty nebulae.
