He directed sunlight through a glass prism to create a spectrum (the rainbow created when light is divided into its colors) and then measured the temperature of each color. Herschel used three thermometers with blackened bulbs (to better absorb heat) and, for each color of the spectrum, placed one bulb in a visible color while the other two were placed beyond the spectrum as control samples. As he measured the individual temperatures of the violet, blue, green, yellow, orange, and red light, he noticed that all of the colors had temperatures higher than the controls. Moreover, he found that the temperatures of the colors increased from the violet to the red part of the spectrum. After noticing this pattern Herschel decided to measure the temperature just beyond the red portion of the spectrum in a region where no sunlight was visible. To his surprise, he found that this region had the highest temperature of all.

Which type of electromagnetic wave is used to produce a thermogram?
To produce thermogram it needs infrared wave. It is a radiant energy which cannot be seen by naked eyes and it was discovered by Sir William Herschel, an astronomer in the year 1800.
What did herschel descover?
infrared
When was infrared invented?
Infrared was invented in the 1980sInfrared was invented in the 1980s
Who discovered the infrared ray and when?
The infrared ray was discovered in 1800 by Sir William Herschel
What did Herschel discover?

Did William Herschel discover Astronomy?
No.
How did sir frederick william herschel discover infrared?
He used blackened light bulbs to measure the heat of the colors in the rainbow/spectrum. He found that red was the hottest. So he did more studies and called it "calorific rays" which later changed to infrared radiation.
Who created infrared besides God?
noone created infrared radiation except God, but it was discovered by Sir William Herschel
What type of wave is a laser?
Infrared wave
Who discovered infrared light?
Sir Frederick William Herschel discovered infrared light in an experiment to measure the temperature of different frequencies of light.
