Law of Reflection Diagram - Physics Education Resource #233001 (License: Personal Use)

This vintage line-drawing diagram depicts the fundamental principle of geometric optics: the law of reflection. Incident rays from a light source labeled 'S' strike a horizontal reflective surface at points A, B, and C, with corresponding reflected rays forming equal angles relative to the normal. Point C shows a specular reflection with visible scattered light, emphasizing surface interaction.

Used in educational contexts-physics textbooks, online science modules, or museum exhibits-to explain how light reflects off smooth surfaces. Matches user intent for learning basic optics, preparing lesson plans, or visualizing ray diagrams.
