Popis:	These waves are used only rarely for two principal reasons. As explained in Section 2.3 the longitudinal waves are always accompanied by oblique transverse waves at a smaller angle and these often generate interfering echoes from geometrical features of the specimen. In addition, if they fall on any reflecting surface at an angle other than 90° they lose energy by mode changing. The zigzag technique for example in plates is not useful and even the corner reflection is poor (Section 2.8, Fig. 2.25).
