This paper is the second of a series describing a quantitative survey of the relations between the optical properties and the other factors of the powders, such as the size and the shape. A beam of a nearly monochromatic light was thrown throhgh a slit on the powder layer composed of the substances adopted in the previous paper. Then, the scattered light reflected backwards the layer with an infinite thickness was photographed on a process plate in an intimate contact with it, and the intensity-distribution was measured by means of photographic photometry. An approximate formula was derived theoretically, giving an intensity of scattered light at a point distant x from the center. It was expressed by [numerical formula] where r_0 is the reflected intensity, at the center, h, the coefflcient of diffusion of light and μ, the parameter of correction meaning the absorption. The agreement of the formula with experimental results was proved satisfactory, and finaly a more convenient, experimental formula was proposed : [numerical formula] The determined values of the parameters expressed reasonably the characteristics of the powder.
