K-band

The K-band refers to a specific range of infrared light in the electromagnetic spectrum, centered around a wavelength of about 2.2 micrometers. It is commonly used in astronomy to observe celestial objects like stars, galaxies, and dust clouds because this range can penetrate dust that blocks visible light. K-band observations help scientists study the composition, temperature, and structure of objects in space. Additionally, some wireless technologies and satellite communications use the term "K-band" to describe frequencies in this spectrum, providing high-capacity data transmission over short and medium distances.
