Crystal diffraction pattern
Webdiffraction pattern, measuring their wavelength, and verifying Eq. 1. As an added bonus, with the principle verified, the diffraction patterns then become powerful tools for the … WebA diffraction pattern is obtained by measuring the intensity of scattered waves as a function of scattering angle. Very strong intensities known as Bragg peaks are obtained in the diffraction pattern at the points where the scattering angles satisfy Bragg condition.
