How a Prism Creates a Rainbow - Science Demonstration #1237706 (License: Personal Use)

In this illustrated demonstration, a person directs sunlight through a triangular glass prism, causing the white light to disperse into its constituent colors-red, orange, yellow, green, blue, indigo, and violet-forming a bright elliptical rainbow. The sun is shown in the upper left corner, with dashed lines indicating the path of light entering and exiting the prism. This visual effectively conveys the principle of optical dispersion as first documented by Isaac Newton.

Used in educational websites, science blogs, and classroom resources to explain light refraction and the visible spectrum; matches user intent for learning basic optics or preparing STEM demonstrations.
