Refraction of Light in Water - Physics Diagram Explained #3808423 (License: Personal Use)

This diagram depicts optical refraction where an orange straw inserted into a transparent glass of water appears bent at the air-water interface. The angle α marks the angle of incidence or refraction, demonstrating Snell’s Law in action. Ripples on the water surface suggest recent disturbance, reinforcing the real-world context of this classic physics demonstration.

Used in educational physics content (e.g., high school or introductory college optics lessons) to explain Snell’s Law, refractive index, and visual perception anomalies. Matches user intent for understanding why objects look displaced underwater.
