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.
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. Beyond the Infrared.
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.

Herschel's telescope will collect infrared radiation from distant stars. 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.
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.
There are several open questions that astronomers hoped to be able to answer by using Herschel to observe in the infrared. When and how did the first galaxies form? The entire sky in infrared light as seen by AKARI. Today, galaxies fill the Universe.
