Understanding Infrared Spectrum Frequency

Infrared (IR) light lies beyond the visible spectrum of light, with wavelengths longer than visible light but shorter than microwaves. IR radiation is divided into near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR), based on wavelength and frequency. Explore differences of Infrared Spectrum Frequencies with NLIR.
