It was Sir William Harschel (discoverer of Urenus), Royal Astronomer of King George III of England who first discovered the infrared rays in 1800 Harschel's most important contributions provided the following findings for the later works:I) he showed that there was satisfactory detector available for investigating the new region of the spectrum by using a sensible mercury in glass thermometer at the different part of spectrum band of suns rays, 2) he raised questions regarding the basic similarity of light and heat. In 1830 Nobili made the first thermocouple based on Seebeck's effect.

Abstract


It was Sir William Harschel (discoverer of Urenus), Royal Astronomer of King George III of England who first discovered the infrared rays in 1800 Harschel's most important contributions provided the following findings for the later works:I) he showed that there was satisfactory detector available for investigating the new region of the spectrum by using a sensible mercury in glass thermometer at the different part of spectrum band of suns rays, 2) he raised questions regarding the basic similarity of light and heat. In 1830 Nobili made the first thermocouple based on Seebeck's effect.
