Abstract

The statistical concentration fluctuations in a solution of polystyrene in cyclohexane near its critical temperature have been directly observed by means of a specially thermostatted phase-contrast optical microscope. A technique which may be of use in the determination of the spatial and temporal persistence of these fluctuations is also described.
