Definition
A ray of light is a narrow beam of light, often represented as a straight line indicating the direction light travels. It is a simplified way to visualize and analyze the behavior of light. Think of it as a single path of light energy. While light actually travels as waves or particles (photons), the 'ray' concept helps understand reflection, refraction, and other optical phenomena. It's like a singular, focused direction for light. Rays of light are fundamental to understanding how light interacts with the world. 🔆
