Prism Light Dispersion Diagram - Physics of Refraction and Color Spectrum #2307377 (License: Personal Use)

This diagram illustrates the classic optical phenomenon where a collimated beam of white light refracts upon entering a transparent triangular prism, separates into its component wavelengths (red to violet), and exits as a fan-shaped rainbow spectrum. The angular deviation increases with shorter wavelengths, causing violet light to bend most and red least. Gray shaded regions indicate internal reflection surfaces within the prism structure.

Used in educational web pages, physics textbooks, and science museum exhibits to explain Snell’s Law, dispersion, and the electromagnetic spectrum; matches user intent for learning basic optics or preparing classroom materials.
