Question

X-rays are used for the study of crystal structure because __________.

• A. X-rays are completely absorbed by the crystal
• B. the wavelength of X-rays is of the same order of magnitude as the interatomic spacing in crystals
• C. the wavelength of X-rays is very small in comparison with the interatomic spacing in crystals
• D. the crystals are completely transparent to X-rays

Answer 1

The correct option is B the wavelength of X-rays is of the same order of magnitude as the interatomic spacing in crystals

As the wavelength of X-rays are of same order as of interatomic spacing in crystals, it can be used to provide the imagery of crystal structure.
