In Bragg's equation (2dSinθ = nλ), ‘n’ represents:

Explanation
Bragg's equation (nλ = 2d sinθ) is derived from Laue equations.
d is the spacing between crystal lattice planes.
Theta is the angle of incidence.
Lambda is the wavelength of the incident wave.
n is an integer representing the order of reflection.
It describes the diffraction of X-rays by crystal lattices.
Max von Laue formulated these equations, which later led to Bragg's Law, explaining X-ray diffraction patterns
