Define Anisotropy, Distinguish between crystalline solids and amorphous solids.

Explanation

Anisotropy : It means difference in properties when measured along the different axes or different directions. These properties vary with different directions. Crystalline solids shows different values of some of the physical properties like electrical resistance, refractive index, when measured along the different directions. The anisotropy arises due to the different arrangement of particles in different directions.
