Two simple harmonic waves are represented by the equations given as y_(1) = 0.3 sin(314 t - 1.57 x) y_(2) = 0.1 sin(314 t - 1.57x + 1.57) where x, y_(1) and y_(2) are in metre and t is in second, then we have

A simple harmonic wave has the equation y_1 = 0.3 sin (314 t - 1.57 x) and another wave has equation y_2= 0.1 sin (314t - 1.57x+1.57) where x,y_1 and y_2 are in metre and t is in second.
