Question

Which of the following statements is appropriate for the crystalline solids?

(a) They give diffraction pattern of broad humps

(b) They give diffraction pattern of sharp lines

(c) They have circular line positions

(d) They have parabolic line positions

This question was posed to me in an interview for internship.

This question is from Survey of Techniques and their Applications to Solids in portion Preparative Methods of Solid State Chemistry

Answer 1

Correct option is (b) They give diffraction pattern of sharp lines

Easy explanation: Crystalline solids give diffraction patterns that have a number of sharp lines. However non-crystalline solids like-glasses, gels give diffraction patterns that have a small number of very broad humps.
