Question

A traveling wave on a long string is described by the time-dependent wave function f1(x,t) = a1sin(b1x - q1t), with a1 = 7.00 Times 10-2 m, b1 = 5 pi m-1, and q. You want a traveling wave of this frequency and wavelength but with amplitude 0.0400 m, and you should add a second traveling wave to the same string in order to achieve this. Its wave function is f2(x,t) = a2 sin(b2x - q2t + Phi i). Calculate the amplitude a2. Express your answer with the appropriate units. Calculate the amplitude a2.
