Summary

Experiments with high-molecular-weight fluids yield large absolute density changes across gas-phase shock waves, producing correspondingly large changes in the index of refraction n. In the experiments described here, the change Δn across the shock is of order 10-2. Simple photography of the shock against a ruled background grid shows a visible shockfront by refraction of the grid lines. Comparison of the photographic image with an image generated by optical ray tracing yields a measurement of the density behind the shock.
