A wave pulse is travelling on a string with a speed v towards the positive X-axis. The shape of the string at t = 0 is given by g(x) = $A s i n (\frac{x}{a})$ where A and a are constants. Write the equation of the wave for a general time t, if the wave speed is v.

A wave propagates on a string in the positive x-direction at a velocity v. The shape of the string at $t = t_{0}$ is given by $g (x, t_{0})$ = A sin $(\frac{x}{a})$ Write the wave equation for a general time t.
