This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 edition. Excerpt: ...out of consideration, and this result may therefore be applied to the motion of a transverse disturbance along a stretched wire, such as that of a pianoforte, where the tension is very great in comparison with the weight of the wire. But the italicized word any, above, gives an excellent example of one of the most difficult parts of the whole subject, viz., the possibility of a solitary wave. This is a question upon which we cannot here enter. If we restrict ourselves to slight disturbances only, theory points out and trial verifies that they are superposable. In fact, in the great majority of investigations which have been made with regard to waves, the disturbances have been assumed to be slight, so that we can avail ourselves of the principle of superposition of small motions (mechanics, 73), which is merely an application of;the mathematical principle of "neglecting the second order of small quantities." The verification by trial is given at once by watching how the ring-ripples produced by two stones thrown into a pool pass through one another without any alteration; that by observation is evident to any one who sees an object in sunlight, when the whole intervening space is full of intense wave-motion. Returning to our wire, let us confine ourselves to a small transverse disturbance, in one plane, and try to discover what happens when the disturbance reaches one of the fixed ends of the wire. Whether a point of the wire be fixed or not does not matter, provided it do not move. In the figure below, two disturbances are shown, moving in opposite directions (and of course with equal speed). Of these, either is the perversion, as well as the inversion, of the other When any part of the one reaches O, the point halfway...
