- v. undergo diffraction
These air bubbles diffract light into colors that reflect back in a flash of iridescence.
We also saw that quantum particles behave like waves—electrons, atoms, and molecules diffract around obstacles and form interference patterns.
Material particles have wave nature and can diffract around objects.
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.
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.
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.
As a result, the waves diffract by a large amount, which is why we can hear sounds even around tight corners.
This is why nobody has ever seen a dog diffract around a tree; nor are we likely to see it any time soon.
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.
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.
