Electromagnetic Induction and Motional EMF
... If the material upon which the sound wave falls is a rigid solid with low density and high incompressibility, the wave may be transmitted for large distances within the material without much attenuation. In general, however, they impinge upon a solid object. As sound waves move away from their sourc ...

... "Then," interrupted Harnett, "if you get electricity at high enough pressure it will squirt off the end of a wire like water out of a fire hose?" "In a way," Gus explained, "only the water will squirt in any old direction, while the high-voltage electric current will only jump across a gap in the ci ...
