Moles. Where n is an integer i.e. 1,2,3,4 etc.
What is N in Bragg's law?
Bragg's law provides the condition for a plane wave to be diffracted by a family of lattice planes: 2 d sin θ = n λ where d is the interplanar spacing, θ the angle between the wave vector of the incident plane wave, ko, and the lattice planes, λ its wavelength and n is an integer, the order of the reflection.
What is Bragg's formula?
But, from geometry, CB and BD are equal to each other and to the distance d times the sine of the reflected angle θ, or d sin θ. Thus, nλ = 2d sin θ, which is the Bragg law.
