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.
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.
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 ...

Herschel also measured temperatures in the region just beyond the red colour where no light was visible and, to his surprise, recorded an even higher temperature there. 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.
Aug 2, 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. Beyond the Infrared

In clever experiments studying what he called “radiant heat” — what we now know as infrared light — Herschel realized there might be light we can’t see. By Kendra Redmond. Published Feb 16, 2024. William Herschel is more famous today for discovering Uranus, but his experiments on the nature of light led to groundbreaking insights.
