Bragg’s law-

Bragg emphasized on parallel planes & the set of planes are considered as Bragg’s planes. When X-rays are allowed to be incident on this planes, diffraction takes place & diffracted pattern gives information about the structure.

Let us consider parallel planes-

Let AB be my incident ray, which …
