Discovering Infrared--the Herschel Experiment
Description:
Visit Discovering Infrared--the Herschel Experiment to learn how infrared radiation was discovered and to find out how you can perform a similar experiment yourself.  When Herschel made a solar spectrum with a prism and shined it on a thermometer, which he placed in different parts of the spectrum, he found the highest temperature just beyond the red, where there was no visible light--yet the intensity of sunlight peaks in the visible. To resolve this discrepancy, see Reconciling the Herschel Experiment.
