Abstract:
Directional radiance factors and polarization are presented for pure silicon carbide powder with an average albedo of 0.15 over a size range from 8 micro to 86 micro, pure aluminum oxide powder with average albedo about 0.85 over a size range from 0.1 micro to 86 micro, and for a mixture of one part silicon carbide to six parts aluminum oxide with average albedo of about 0.40 over a size range from 5 micro to 86 micro.

Potential Due to a Polarized Object
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...
Measuring Reaction Rates
Polarimetry finds application in chemical kinetics to measure the concentration and reaction kinetics of optically active substances during a chemical reaction. Optically active substances have the capability of rotating the plane of polarization of linearly polarized light passing through them—a feature called optical rotation. Optical activity is attributed to the molecular structure of substances. Normal monochromatic light is unpolarized and possesses oscillations of the electrical field in...
