HAP. Harmonic waves in a string.—In dealing with transverse waves ingeneral, it was seen that a harmonic wave could be represented bythe equation /1 ~\ y-a am 2» ^-|), (p. 682) and that the motion of a point on the string is represented by the equation t/ = a sin 27r obtained by putting x = 0. Now,… … ^«S/»2r(|+|J j/z=aSin2w( Fig. 671.—Two waves arising at a vibrating point. a simple harmonic manner along the axis OY, one wave will traveltowards the right, that is, in the positive direction of x, and theother towards the left, that is, in the negative direction of x.The former wave has the…
