Refraction Explained: Why Objects Look Bent in Water #3498595 (License: Personal Use)

This educational illustration shows a red-and-purple pencil partially submerged in a transparent glass of water, with the portion underwater appearing displaced and angled relative to the part above the surface. The phenomenon occurs because light travels slower in water than in air, causing rays to bend at the air-water interface, altering the apparent position of the submerged segment. The image clearly labels “Refraction” to reinforce the core concept for learners.

Used in science education websites, physics lesson plans, or STEM outreach materials to visually explain optical refraction; targets students, teachers, and curious learners seeking intuitive understanding of wave behavior.
