For the structural analysis of crystal, X−rays are used bacause : (a) X−rays have wavelength of the order of interatomic spacing (b) X−rays are highly penetrating radiations (c) wavelength of X−rays is of the order of nuclear size (d) X−rays are coherent radiations |

It happens so in case of crystals. So, X-rays are used for structural analysis of crystals.</span></span></p> | |
