From theCambridge English Corpus With zero flow, diffracted waves were spherical as expected. From theCambridge English Corpus The objects they encounter will either absorb, reflect ordiffractthem. From theCambridge English Corpus Furthermore, the rhinoceros does not suffer from the quality of the marine medium diffusing and diffracting light, as does the dolphin. From theCambridge English Corpus The supersonic patch and the fan are embedded inside an apparently continuous self-similar diffracted wave pattern behind the triple point. From theCambridge English Corpus The shock wave is diffracting around the pressure-gauge holder in this figure and the shock wave reflected from the face of the holder is moving back towards the exploding sphere. From theCambridge English Corpus Equation (4.12) represents a diffracted field, (4.13) incident and diffracted fields and (4.14) incident, reflected and diffracted fields. From theCambridge English Corpus During the equalization of the pressures behind the reflected and diffracted shock waves, a vortex is formed as the flow separates around the front edge of the gauge holder.
