Most students find it difficult to deal in vector space, but in this situation it is mandatory to understand the famous Bragg's law. A mirror reflects light at all angles (except at extremely low incident angles) but the equidistant lattice plane of atoms will diffract the incoming beam of X-rays only when the Bragg's law is satisfied. That's the genius of son Bragg's Nobel prize winning invention. In fact both the father Bragg and son Bragg got Nobel prize in physics for the understanding of X-ray diffraction theory. Never happened like (both father and son getting Nobel) that in the history of the science ever.

lattice plane scattered X rays in all direction but only some direction satisfy braggs law ,I that that should be the right statement, correct me if I am wrong

sir if the magnitude of the incident and reflected wave vector is same. Shouldn't delta K be zero ?

The magnitude is the same but directions are different. Delta K is difference between two vectors.
