MT.aps X-ray diffraction

Bragg's law is the basis for the study of crystal structures by x-ray diffraction.

This application allows studying how the constructive and distractive interference of x-ray occurs in crystals. Change the angle of the incoming x-ray beam, the spacing of the atomic planes, or the wave length of the x-ray and see their immediate effect on the reflected beam.
Additional atomic layers can be added, to represent more complex crystal structures.

Have fun!
