What is the wavelength range of infrared radiation?

The wavelength range of infrared radiation spans from approximately 0.72 to 1,000 micrometers. This broad range encompasses various types of infrared radiation, including near-infrared, mid-infrared, and far-infrared. The near-infrared region begins just beyond the visible spectrum, starting from about 0.72 micrometers, which is just outside the visible light range, and extends into the mid and far-infrared ranges that cover up to 1,000 micrometers.

This range is significant in multiple applications, including thermal imaging, remote sensing, and communication technologies, among others. Understanding the infrared range is essential for the effective use of these technologies, as different applications may utilize different parts of the infrared spectrum depending on the specific requirements of the technology involved.
