  1. Diffraction - Wikipedia

    Diffraction is the deviation of waves from straight-line propagation without any change in their energy due to an obstacle or through an aperture. The diffracting object or aperture effectively …

  2. Diffraction | Definition, Examples, Types, & Facts | Britannica

    Diffraction, the spreading of waves around obstacles. Diffraction takes place with sound; with electromagnetic radiation, such as light, X-rays, and gamma rays; and with very small moving …

  3. What Is Diffraction? The Physics of Spreading Waves

    2025年5月27日 · Diffraction is the phenomenon where waves bend, spread, or interfere when they encounter an obstacle or pass through a narrow opening. The effect is subtle yet profound.

  4. 17.1 Understanding Diffraction and Interference - OpenStax

    The bending of a wave around the edges of an opening or an obstacle is called diffraction. Diffraction is a wave characteristic that occurs for all types of waves. If diffraction is observed …

  5. What is diffraction in physics? - California Learning Resource …

    2025年7月2日 · Fraunhofer diffraction is commonly observed in applications involving lenses and telescopes, where focusing elements effectively bring the observation point to infinity. The …

  6. Diffraction - University of Tennessee

    Diffraction is the tendency of a wave emitted from a finite source or passing through a finite aperture to spread out as it propagates. Diffraction results from the interference of an infinite …

  7. Diffraction of light - GeeksforGeeks

    2025年7月23日 · Diffraction describes a specialized case of light scattering in which an object with regularly repeating features (such as a diffraction grating) produces an orderly diffraction of …

  8. Diffraction - Math is Fun

    Diffraction is when waves bend around the corner of an obstacle. ... It is most easily seen when a wave spreads out after passing through a gap.

  9. 7.4: Diffraction - Physics LibreTexts

    This page explains the phenomenon of diffraction, where waves can bend and change direction without affecting their speed. It illustrates how sound waves can travel through openings, …

  10. Diffraction in Physics: Definition, Types & Easy Examples - Vedantu

    Diffraction Meaning: It is the process by which a stream of light or wave is spread out as a result of passing via a narrow area or across an edge, generally accompanied by interference …
