bragg angle sentence in Hindi

Examples

1. Apart from the Darwin width of the reflection, the width of single dislocation images may additionally depend on the Burgers vector of the dislocation, i . e . both its length and its orientation ( relative to the scattering vector ), and, in plane wave topography, on the angular departure from the exact Bragg angle.
2. The Kikuchi band widths themselves ( roughly " ?L / d " where " ? / d " is approximately twice the Bragg angle for the corresponding plane ) are well under 1? because the wavelength " ? " of electrons ( about 1.97 picometres in this case ) is much less than the lattice plane d-spacing itself.
