| Abstract: | We report an experimental measurement, based on an interferometric technique, for the determination of the temperature dependence of the refractive index n
L
of a liquid suspension of dielectric spheres in the thermal range 20–52° C. In this range we have measured values of  n
L
/T of order of magnitude 10–4° C–1. The observed values are compared with those obtained for water. |
