==Key Stage 5==
===Meaning===
[[Diffraction]] is the spreading of [[wave]]s when they pass through a gap or around an obstacle.
===About Diffraction===
*'''Diffraction''' occurs with all types of [[wave]]s, including [[Visible Light|light]], [[sound]], and [[Water Wave|water waves]].
*'''Diffraction''' is evidence for the wave-like behaviour of [[matter]].
*The extent of '''diffraction''' depends on the [[wavelength]] of the [[wave]] and the size of the gap or obstacle.
*'''Diffraction''' is most noticeable when the gap size is comparable to the [[wavelength]].
*'''Diffraction''' explains phenomena such as the bending of [[Visible Light|light]] around corners and the formation of [[Diffraction Pattern|diffraction patterns]].
*'''Diffraction''' is used in various applications, including [[X-ray Diffraction|X-ray diffraction]] to determine crystal structures and [[Electron Diffraction|electron diffraction]] to study the properties of materials.

===Examples===

*The [[Diffraction Pattern|diffraction pattern]] observed when [[Visible Light|light]] passes through a [[Single Slit Diffraction|single slit]].
*[[Diffraction]] of [[sound]] [[wave]]s allows us to hear around corners.
