  • question_answer
    The first three nearest neighbor distance for primitive cubic lattice are respectively (edge length of unit cell = a):

    A) \[a,\,\sqrt{2}a,\sqrt{3}a\]

    B) \[\sqrt{3}a,\,\sqrt{2}a,\,a\]

    C) \[a,\,\sqrt{2}a,2\,a\]

    D) \[a,\,\sqrt{3}a,2\,a\]

    Correct Answer: A

    Solution :

    [a]       
    \[AB=a\]           (Nearest)
    \[BD=\sqrt{2}a\]            (Next-nearest)
    \[CE=\sqrt{3}a\]            (Next-next-nearest)
