Webbpeaks is one wavelength, λ = 0.75 m. The amplitude of a wave is given by the height of the peak, so A = 0.025 m. Next recall that the formula for a wave on a string is given by y = Asin(kx ± ωt + φ0). For waves moving to the left, we need the + sign. Webbto the positive half-line are ˚(x) and (x) respectively. Finally, v(x;t) solves the wave equation for x>0, since u(x;t) satisfies the wave equation for all x2R, and in particular for x>0. Thus, v(x;t) defined by (1.4) is a solution of the Dirichlet problem (1.1). It is clear that the solution must be unique, since the odd extension
