2 presents a good mix of materials and their basic reflective properties. There are
many factors that affect an item??™s reflectivity, so use these values as a starting point.

Refraction Properties
Table A.3 provides a rather extensive list of items. Chances are you won??™t need most of
them until someone comes along from a scientific institution wanting work done that has
to be scientifically accurate. You??™ll be glad you have this list then!
Indices of refraction for various elements, materials, liquids, and gases at Standard
Temperature and Pressure (STP) in visible light are listed.
