[Back-formation from diffraction.]

Examples

  • These air bubbles diffract light into colors that reflect back in a flash of iridescence.

    Birdology

  • Following the experiments of Davisson and Germer and Thomson, scientists showed that all subatomic particles behave like waves: beams of protons and neutrons will diffract off samples of atoms in exactly the same way that electrons do.

  • A dog can hear a potato chip hitting the kitchen floor from the living room because sound waves diffract through the kitchen door and around corners.

    How to Teach Physics to Your Dog

  • For example if two people stand back-to-back in an open field with no large objects to reflect or diffract the sound waves, they can still hold a conversation.

  • This is why nobody has ever seen a dog diffract around a tree; nor are we likely to see it any time soon.

    How to Teach Physics to Your Dog

  • On the right, a wave with a long wavelength encounters an opening comparable to the wavelength, and the waves diffract through a large range of directions.

    How to Teach Physics to Your Dog

  • We also saw that quantum particles behave like waves—electrons, atoms, and molecules diffract around obstacles and form interference patterns.

    How to Teach Physics to Your Dog

  • Similarly, if sound waves encounter an obstacle like a chair or a tree, they will diffract around it, provided the object is not too much larger than the wavelength.

    How to Teach Physics to Your Dog

  • Material particles have wave nature and can diffract around objects.

    How to Teach Physics to Your Dog

  • As a result, the waves diffract by a large amount, which is why we can hear sounds even around tight corners.
