Introduction to Infrared Light nm

Understanding Infrared Light nm

Infrared light, often referred to as infrared radiation, is a form of electromagnetic radiation with wavelengths longer than those of visible light but shorter than those of terahertz radiation. The term "nm" stands for nanometers, which is a unit of length in the metric system equal to one billionth of a meter. In the context of infrared light, nm refers to the specific wavelength range within which infrared radiation is categorized. This article aims to provide an in-depth introduction to the field of infrared light nm, exploring its applications, technological advancements, and future prospects.
