Abstract
The phase of the photoacoustic signal is measured as a function of chopping frequency for different thicknesses of Pb resting on a water backing. Analysis of the results is in agreement with the theory of Rosencwaig and Gersho [J. Appl. Phys. 47, 64 (1976)] and leads to a simultaneous determination of thermal conductivity and specific heat of the sample.Keywords
