MoreFAQ
What is Bragg Law used for?
Bragg Law is used to calculate diffraction angles or d-spacings for a crystal structure when two parameters of Bragg's Law (λ = 2d sin(θ)) are known. It helps in understanding the relationship between wavelength, interplanar spacing, and diffraction angle.
What types of plots can Bragg Law generate?
Bragg Law can generate plots of the rocking curve, mirror reflectivity, F(000), µ, powder pattern, stereographic projection, Laue pattern, multiple reflections, and a 3D model of the unit cell and 1st Brillouin zone.
Does Bragg Law support both X-rays and Neutrons?
Yes, Bragg Law includes atomic structure factors for both X-rays and Neutrons, making it versatile for different types of diffraction experiments.
