SUMMARY
The Davisson-Germer experiment and Bragg's law both describe the conditions for constructive interference in wave diffraction, yet they differ in their formulations. The Davisson-Germer experiment uses the equation dsin(theta) = n(wavelength), while Bragg's law employs 2dsin(theta) = n(wavelength). This distinction arises because Bragg's law applies to the diffraction of X-rays between crystal layers, whereas the Davisson-Germer experiment focuses on electron diffraction at atomic distances. Understanding these differences is crucial for interpreting diffraction patterns in crystallography.
