A) its energy is high
B) it can penetrate the material
C) its wavelength is comparable to in teratomic 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) is crystals. Radiation of longer wavelength cannot resolve the details of structure, while radiation of much shorter wavelength is diffracted thorugh inconveniently small angles. Usually diffraction of X-rays is employed in the study of crystal structure as X-rays have wavelength comparable to interatomic spacing.You need to login to perform this action.
