Infrared radiation has wavelengths ranging from approximately 700 nm to 1 mm.
It is divided into three categories: near-infrared, mid-infrared, and far-infrared.
Infrared radiation is emitted by all objects with a temperature above absolute zero due to thermal motion.
It plays a significant role in heat transfer processes, including radiation from the Sun and heating applications on Earth.
Infrared spectroscopy is used in scientific research to identify and study chemical substances.
