All objects, provided their temperature is above absolute zero (0 K, −273°C) emit radiations part of which can be perceived by special instruments.无聊的人 发表于 2025-3-23 14:55:12

https://doi.org/10.1007/978-3-658-36145-7The ultraviolet was recognized in 1801 by J. W. Ritter, who observed the chemical activity of this shortwave radiation. In the previous year, Sir Frederich William Herschel, breaking down light with a prism, noticed that next to the red was a zone where the thermometer showed up hitherto unsuspected energy.FECT 发表于 2025-3-24 11:17:40
Goethe-Gesellschaft und Gegenwart,We have already looked at the central topics in regard to centi-millimetric waves; we now need only clarify some ideas on the near and middle infrared, which is now being exploited intensively.温室 发表于 2025-3-24 16:57:10
