Visible Light Spectrum Intensity Graph - Physics & Optics Reference #3271321 (License: Personal Use)

The plot shows two distinct intensity peaks: a broad main peak spanning 400-600 nm (violet to green-yellow), representing typical daylight or blackbody emission, and a secondary peak beyond 650 nm in the red/near-infrared region, possibly indicating LED emission or thermal radiation. Wavelength is measured in nanometers (nm) on the x-axis, while intensity is normalized on the y-axis.

Used in educational materials, physics textbooks, and optics webpages to explain spectral distribution, human vision sensitivity, or light source characteristics; matches user intent for learning about light spectra, color theory, or sensor response curves.
