When are X-rays used in crystallography?
Correct answer: D. To perform diffraction
- A. To prevent interference
- B. To prevent diffraction
- C. To perform interference
- D. To perform diffraction
Explanation
X-ray beams are used to determine the structure of the crystal. The crystal diffracts the X-ray beams and the intensities and angle of diffraction of these diffracted beams is studied to estimate the structure of the crystal so the answer is D.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
