Question

Does diffraction occurs only when xray is used as source?

Answer 1

Answer:yes,

these specific directions appear as spots on the diffraction pattern called reflections. ... X-rays are used to produce the diffraction pattern because their wavelength λ is typically the same order of magnitude (1–100 angstroms) as the spacing d between planes in the crystal.
