X-ray spectrum — UPSC IFoS 2014 Physics PYQ
Buy PYQ Solution Manual →X-ray of wavelength 1\cdot 4\text{ \AA} is found to be Bragg reflected from (111) plane of an fcc structure. If the lattice parameter of the crystal is 5\text{ \AA}, find the angle at which the X-ray beam is incident on the (111) plane of the crystal.
