Light prisms are optical devices that demonstrate the dispersion of white light into a spectrum of colors. This process, governed by the refractive index and Snell's Law, reveals the composite nature of light and its interaction with matter. Prisms have been crucial in advancing our understanding of light's fundamental characteristics, with practical applications in spectroscopy and optical design.
