Electromagnetic Spectrum Explained: UV, Visible, and Infrared Light #1876718 (License: Personal Use)

This diagram illustrates how solar radiation spans wavelengths from 100 nm (UVC) to over 700 nm (infrared), with the visible spectrum occupying a narrow band between 400-700 nm. Ultraviolet is subdivided into UVC (100-280 nm), UVB (280-315 nm), and UVA (315-400 nm), while infrared begins beyond 700 nm. The sun is shown as the primary natural source emitting all these bands.
