kaukoinfrapuna

Kaukoinfrapuna refers to the far-infrared portion of the electromagnetic spectrum, typically spanning wavelengths from 25 micrometers to 1 millimeter. This region is also known as the submillimeter wave or FIR. It lies between the microwave and the visible light spectrum. Objects at room temperature emit radiation in the far-infrared range, making it significant for studying cooler celestial objects, such as interstellar dust clouds, asteroids, and planets. In Earth sciences, far-infrared radiation plays a role in atmospheric studies and remote sensing of the Earth's surface. Its applications extend to thermal imaging, spectroscopy, and astronomy. Specialized detectors are required to observe far-infrared radiation due to its low energy. The Earth's atmosphere is largely opaque to much of the far-infrared spectrum, necessitating observations from high-altitude aircraft or space telescopes.
