در فیزیک '''قانون براگ''' نتایج آزمایشاتی است که از تابش [[پرتو ایکس]] یا [[نوترون]] به سطح [[بلور]]ین تابیده می شد derived by physicist [[William Lawrence Bragg|Sir William Lawrence Bragg]] <ref> There are some sources, like the ''Academic American Encyclopedia'', that attribute the discovery of the law to both W.L Bragg and his father W.H. Bragg, but the official [http://nobelprize.org/nobel_prizes/physics/laureates/1915/present.html Nobel Prize site] and the biographies written about him (''Light Is a Messenger: The Life and Science of William Lawrence Bragg'', Graeme K. Hunter, 2004 and “Great Solid State Physicists of the 20th Century", Julio Antonio Gonzalo, Carmen Aragó López) make a clear statement that William Lawrence Bragg alone derived the law. </ref> in [[1912]] and first presented on [[1912-11-11]] to the [[Cambridge Philosophical Society]]. Although simple, Bragg's law confirmed the existence of real [[Subatomic particle|particle]]s at the atomic scale, as well as providing a powerful new tool for studying [[crystal]]s in the form of [[X-ray diffraction|X-ray]] and [[neutron diffraction]]. William Lawrence Bragg and his father, [[William Henry Bragg|Sir William Henry Bragg]], were awarded the [[Nobel Prize]] in [[physics]] in [[1915]] for their work in determining crystal structures beginning with [[Sodium chloride|NaCl]], [[Zinc sulfide|ZnS]], and [[diamond]].
