The basic idea is the same, the only difference being that the particles now don't oscillate along the yaxis as in transverse waves, they now do so in the xaxis itself So, instead of y (x,t) we use x (x,t) But that equation is very confusing since you can't know which is. The equation y(x,t)=Acos2πf(xv−t) may be written as y(x,t)=Acos2πλ(x−vt) a Use the last expression for y(x,t) to find an expression for the transverse velocity v y of a particle in the string on which the wave travels Express your answer in terms of the variables A, v, λ, x, t, and appropriate constants. (1216) y x y 0 cosx y 0 sinx If y x eix is to represent a solution of this differential equation, we have y 0 e0 1, and y 0 ie0 i, so we must have (1217) eix cosx isinx Notice that if we differentiate this expression, we get (1218) sinx icosx i cosx isinx so this expression is consistent with the differentiation rule for the exponential (12.
