Solution

Your question is not clear.I hope this helps...

Some crystalline solids are anisotropicbecause despite showing periodicity they are not exactly the same in all directions. It all depends on the symmetry of the unit cell of the crystal. If its size in the x, y and z direction is not same, it would be anisotropic .
