Dynamic photoelastic measurements of Rayleigh wave propagation in a series of seventeen seismic models of wedges have been described. Transmission and reflection coefficients based on both stress and displacement were established for wedges with included angles ranging from 40° to 180°. The results indicate that the transmission and reflection coefficients are rapidly changing functions of the wedge angle. The experimental results for the transmission and reflection coefficients agree remarkably well with previous experimental work using crystal transducers. Comparisons of the experimental results with theoretical predictions of A. K. Mal and L. Knopoff (1966) in most cases showed reasonable agreement.
