Abstract
An experimental study of the front of a refracted shock wave has been carried out in a shock tube. The refracted shock wave was generated by the shock passage through a sinusoidal discontinuous interface from a light to a heavy gas. To determine the amplitude of the refracted wave as a function of the wave travel path, Schlieren pictures were used. The decay of the amplitude was inversely proportional to the density ratio. After travelling a distance of 3λ, the refracted shock wave became plane.
