A mathematical model simulating light transmission through liquid‐liquid dispersions has been developed. Numerical solutions of the model for various drop size distributions show that the fraction of parallel light which passes through a dispersion is a unique function of a dimensionless group, here named the Transmission Number, regardless of the drop size distribution. The results, which were verified by actual light transmission experiments, show that the interfacial area of a liquid‐liquid dispersion can be calculated from a light reading provided that the light detector receives only parallel light. Application of the results to other two‐phase dispersions is indicated.
