What Does “Refraction” Really Mean?
“Refraction” is the bending or change of direction of waves—most commonly light or sound—when they pass from one medium to another. It is a fundamental concept in physics, optics, and wave mechanics.
Key traits include:
- Bending: The change in trajectory of waves
- Deviation: Shift from a straight-line path
- Distortion: Alteration of the wave’s original path or shape
Think of refraction as the phenomenon that makes a straw look bent in a glass of water or creates rainbows from sunlight passing through raindrops.
