A) its energy is high
B) it can penetrate the material
C) its wavelength is comparable to interatomic distance
D) its frequency is low
Correct Answer: C
Solution :
Crystal structure is explored through the diffraction of waves having a wavelength comparable with the interatomic spacing \[\ ({{10}^{-10}}\,m)\] in crystals. Radiation of longer wavelength cannot reslove the details of structure, while radiation of much shorter wavelength is diffracted through inconveniently small angles. Usually diffraction of X-ray is employed in the study of crystal structure as X-ray have wavelength camparable to interatomic spacing.You need to login to perform this action.
