Question

any one can explain about Bragg's equation. today I have chemistry exam​

Answer 1

Answer:

In physics, Bragg's law, or Wulff–Bragg's condition, a special case of Laue diffraction, gives the angles for coherent and incoherent scattering from a crystal lattice. When X-rays are incident on an atom, they make the electronic cloud move, as does any electromagnetic wave.

Answer 2

Answer:

I hope it helps you please follow me

Explanation:

A simple way to derive the Bragg equation is as follows. The path difference between electrons scattered from adjacent crystal planes is 2d sin θ. For constructive interference between the two scattered beams the difference must be an integer multiple of electron wavelengths, nλ which gives the Bragg equation.
