infrared
의미: Electromagnetic radiation with wavelengths longer than visible red light but shorter than microwaves, perceived as heat and widely used in thermal imaging, remote controls, and spectroscopy.
Infrared radiation occupies the spectrum between roughly 700 nanometres and 1 millimetre. It is divided into near-infrared, mid-infrared, and far-infrared bands, each with distinct applications. Thermal cameras detect infrared emissions to visualise heat signatures, making them invaluable in building surveys, search and rescue, and military surveillance. The term functions as both an adjective and a noun.
