This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 edition. Excerpt: ... the distance from the upper fixed end to the fingers corresponds to nea rly a half wave length; when vibrating in two segments the distance corresponds to a whole wave length; and when vibrating in three segments it corresponds to one and a half wave lengths. Since in the formula v=f, where v is the velocity of propogation, A the wave length, and f the frequency; v is constant, show the relation between A and f in any set of observations. In paragraphs 275 and 276 (Watson's Physics) it is shown that T v=s/--; that is, that v varies with the square root of the tenm sion. Verify this from the data taken. Take the suspended mass off and from the upper end of the the rope produce stationary waves having one, two and three nodes between the upper and lower ends, note carefully the positions of the nodes in each case. What portions of a wave length does the rope vibrate in, in each case? Stationai y Waves, Longitudinal. A coil of wire is suspended with its axis horizontal. With both ends of the coil free to vibrate, strike one end a light blow and note the progress of the wave. The reflection of the wave will be at an " open" end and therefore " without change of phase." By striking one end at the proper intervals produce stationary waves, first with one node between the ends, then with two nodes and finally with three nodes between the ends. In each case count the number of vibrations in 15 seconds, repeating the observations at least three times. Note the relation between the length of the coil and the wave length; also between the wave lengths and frequencies. Repeat the above observations with one end of the coil fixed. In all cases be sure that the vibrations are not forced. Show diagramatically the production of the...
