Visible light from a helium-neon laser was directed onto a white-card surface capable of rotation, and the granularity characteristics of the scattered light were observed. Photographs are given showing the degree of granularity observed under various rotational speeds. It is indicated that the visible granularity, due to the extremely high degree of coherence of the laser light, disappears from view as a consequence of persistence of vision when the light is scattered by a moving surface. Additional observations relating to the phenomenon of granularity are also presented and discussed.
