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.

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.
The infrared pioneers-I. Sir William Herschel 3 arrival in 1772 until his death, she was his indispensable assistant in his astronomical work. The lack of equipment and the lack of instruction were formidable barriers, but after about 200 partial failures, Herschel achieved a satisfactory mirror for his first telescope in 1774, a 5-5 ft focal ...
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.
