Introduction to Infrared Light nm

What is Infrared Light nm?

Infrared light, denoted as "infrared light nm," refers to a segment of the electromagnetic spectrum that lies between visible light and microwave radiation. It spans wavelengths from 700 nanometers (nm) to 1 millimeter (mm). This type of light is invisible to the human eye, as it falls outside the range of visible light wavelengths, which are between 380 nm and 750 nm. Despite its invisibility, infrared light plays a crucial role in various applications, including communication, medical diagnostics, and environmental monitoring.
