The structure of solids is investigated by using (a) cosmic rays (b) X-rays (c) γ -rays (d) infra-red radiations

Answer: (b). X-ray wavelength ( ~ 1 Å) is of the order of interatomic spacing in crystals. So X-rays diffract from crystal planes (Bragg diffraction) and reveal the structure. So the answer is (b) X-rays.

The structure of solids is investigated by using

Show answer and solution

Answer: (b)

X-ray wavelength ( $\sim 1\ \text{Å}$ ) is of the order of interatomic spacing in crystals.
So X-rays diffract from crystal planes (Bragg diffraction) and reveal the structure.
So the answer is (b) X-rays.
