Webb13 juli 2024 · Since the emitted sound waves usually propagate slower in the delay wedge (or in the wear resisting plate) than in the workpiece, a refraction away from the normal of the boundary takes place. Furthermore, the sound wave no longer propagates as a longitudinal wave but as a transverse wave.
