1.	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
Answer» Correct option (a) X−rays have wavelength of the order of interatomic spacing Explanation: The diffraction of X-rays can take place only when spacing between two adjacent planes is of the order of wavelength of X-rays. It happens so in case of crystals. So, X-rays are used for structural analysis of crystals.

Answer»

Correct option (a) X−rays have wavelength of the order of interatomic spacing

Explanation:

The diffraction of X-rays can take place only when spacing between two adjacent planes is of the order of wavelength of X-rays. It happens so in case of crystals. So, X-rays are used for structural analysis of crystals.
