WebThe Discovery of Infrared Light William Herschel (1738 - 1822) was one of the most important astronomers that ever lived. In 1800 he performed a famous experiment where he tried to measure the temperature of different colors of the spectrum by placing a thermometer on each colour.

Herschel made repeat measurements with the thermometer bulb in the violet, green and red regions of the spectrum. In each, he observed a temperature rise, which he recorded after 8 minutes. Average rise in red: 6.9°F, in green: 3.2°F , and in violet: 2°F. He concluded that the red rays of sunlight have a … Ver mais When visible light falls on a surface, some of it may be absorbed; the surface is warmed. A thermometer left lying in sunlight shows an increasing temperature. Today, we would say … Ver mais Herschel found that the heating effect of these invisible rays was greatest at a point beyond the red end of the visible spectrum, and … Ver mais Before experimenting with his filters, Herschel needed to know about the heating effect of different colours of light. Did different regions of the spectrum have equal heating effects? He set up an experiment in which … Ver mais Physicists’ understanding of the electromagnetic spectrum has extended gradually over the two centuries since Herschel’s work. … Ver mais WebHow did William Herschel discover infrared radiation? He did an experiment where he used a prism to split sunlight into a spectrum and then put a thermometer in each of the colours in turn. He also put a thermometer just beyond the red end of the spectrum, where there was no visible light.
