Summary
The aim of performed experiments was to visualize, record and analyse the P wave pattern connected with simple block structures. Two-component plate models of a half-space (turpentine, v1=1240 m/s) containing rectangular blocks (perspex, v2=2630 m/s) were studied by means of the schlieren method. P waves generated by an exploding wire source were recorded with a high-speed camera during their passage through a block. The field of reflected and refracted waves, head waves, diffracted waves and inhomogeneous waves was analysed for waves entering and leaving the block. Special attention was paid to diffraction phenomena on rectangular corners of the blocks in question.
