Explain anisotropy in crystalline solids.

A crystalline solid

Crystalline solids have

How many types of Bravais lattices can occur in crystalline solids?

Which one is not property of crystalline solid?

The violet crystalline solid is

Why amorphous solids are called isotropic whereas crystalline solids are called anisotropic ?

Assertion: Crystalline solids can cause X-rays to diffract. Reason: Interatomic distance in crystalline solids is of the order of 0.1nm .

Classify the following solids into amorphous or crystalline solids. Bakelite, Platinum , Camphor , Oxalic acid , Melamine formaldehyde, Alum , Neoprene, Sugar , Solid CO_2 , Polythene.

An X-ray beam (lambda = 70.9 p m) was scattered by a crystalline solid. The angle (2theta) of the diffraction for a second order reflection is 14.66^(0) . Calculate the distance between parallel planes of atoms of the crystalline solid.
