Refraction of Light Explained with Simple Demonstration #3498585 (License: Personal Use)

This hand-drawn illustration depicts a yellow pencil partially submerged in a clear glass of blue water, visually demonstrating how light rays change speed and direction at the air-water interface, causing the pencil to appear displaced or bent. The image highlights the fundamental optical phenomenon of refraction, governed by Snell’s Law, where the refractive index difference between two media alters the path of light. Such visuals are commonly used in physics education to introduce wave behavior and optical principles.

Used in educational websites, science blogs, or classroom resources explaining optics; matches user intent for visual learning, homework help, or conceptual clarification of refraction.
