The scattering of light by liquid and solid surfaces

Abstract

It is a well-known fact of observation that most reflecting surfaces usually also scatter a little light and are thus rendered visible. The effect is usually dismissed, however, as due to dust or imperfect polish of the surface, and little attention has been given to the problem of determining whether, when these disturbing factors are eliminated, any scattering by the surface persists. Experiments carried out by the writer in collaboration with Mr. L. A. Ramdas to test this matter have led to some interesting results.
