Examples of Refraction

Refraction is the bending of light as it passes from one material into another—like from air into water or glass. This happens because light changes speed when it enters a material with a different density. Refraction helps us understand how lenses, glasses, magnifying gla...

Refraction is the bending of light as it travels from one medium to another, and it's seen in many examples around us.

Try this: Put a pencil in a glass of water. It will appear bent or shifted at the surface. That's due to refraction—the light changes direction as it moves from water to air, making the pencil appear bent.
