  1. Refraction - Wikipedia

    In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. [1]

  2. Refraction | Definition, Examples, & Facts | Britannica

    Dec 26, 2025 · refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves travel faster in deep water than …

  3. What Is Refraction in Physics? The Bending of Light Explained

    May 26, 2025 · Refraction is one of the fundamental phenomena in physics that governs how light behaves when it travels through different materials. At its core, refraction is the bending of light …

  4. Refraction: What It Is and Why Light Bends - All About Vision

    Sep 10, 2025 · Learn what refraction is, why light bends and how it affects vision, lenses, rainbows and other parts of your everyday life.

  5. Refraction - Math is Fun

    Refraction is the "bending" of light (or any electromagnetic wave) when entering a different medium. When electromagnetic waves enter a different medium the speed changes. The …

  6. Physics Tutorial: Refraction and the Ray Model of Light

    The ray nature of light is used to explain how light refracts at planar and curved surfaces; Snell's law and refraction principles are used to explain a variety of real-world phenomena; refraction …

  7. 16.2 Refraction - Physics | OpenStax

    The changing of a light ray’s direction (loosely called bending) when it passes a boundary between materials of different composition, or between layers in single material where there …

  8. Refraction – Definition, Refractive Index, Snell’s Law

    Oct 20, 2021 · In physics, refraction is the change in speed and direction of a wave as it enters a new medium. Perhaps the most familiar example is the refraction of white light in a prism, …

  9. RefractionThe Physics Hypertextbook

    Refraction is the change in direction of a wave caused by a change in speed as the wave passes from one medium to another. Snell's law describes this change.

  10. What Is Refraction? - BYJU'S

    We can define refraction as the phenomenon of bending of light when it passes from one substance to another. Rainbow, mirage are a few real-life examples of refraction.
