Why Crystalline Solids Are Called Anisotropic?

d) Crystalline solids are anisotropic in nature. It is because the arrangement of constituent particles is regular and ordered along all the directions. Therefore, the value of any physical property (electrical resistance or refractive index) would be different along each direction (Fig. 2) .

Why amorphous solids are anisotropic?

Since the arrangement of particles is different along different directions, the value of the physical properties is found to be the same along each direction. ... This property is known as isotropy. Therefore, the statement amorphous solids are isotropic in nature is true.

Why crystalline solids are called?

Crystalline solids

The smallest repeating structure of a solid is called a unit cell, which is like a brick in a wall. Unit cells combine to form a network called a crystal lattice. ... Because of the repeating geometric structure of the crystal, all the bonds between the particles have equal strength.
