Proposed by William Lawrence Bragg and his father, William Henry Bragg, in 1913, Bragg&#8217;s Law opened a new era of scientific inquiry and revolutionized our understanding of crystal structures.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:240,&quot;335559739&quot;:240,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">At its core, Bragg&#8217;s Law describes the constructive interference between X-rays or electrons and the regularly spaced atomic planes within a crystal lattice.
