2. • There are many ways to classify solids, but the broadest
categories are crystalline solids, those with a highly
regular arrangement of their components, and
amorphous solids, those with a considerable disorder in
their structure.
• So we have 2 main types of solids.
9. • So what’s a lattice?
• Simply, it’s this:
• The nucleus of Rhodium.
Which is: a 3 dimensional shape showing you the positions
of the stuff that makes up the substance.

light are scattered from a regular
array of points in which the
spacings between the
components are comparable with
the wavelength of the light.
