sci.d-spacing-Bragg-law Calculator
Calculates X-ray or neutron diffraction peak angles from d-spacing using Bragg's law: nλ = 2d sin θ. Cu Kα radiation (λ = 1.542 Å) diffracted at θ = 20° from a plane with d = 2.25 Å — systematic absences in diffraction patterns reveal crystal symmetry.
Inputs
Lambda Angstrom
Distance between successive wave crests. Related to frequency: λ = speed / frequency.
Theta Deg
