The term 'Bragg reflection' is a carryover from the simplified Bragg derivation for diffraction. In fact, it is not really a reflection but a diffraction intensity. Explain the difference between diffraction and reflection by commenting on the origins of the phenomena, the angles involved and the intensity of the beams in and out
