A snapshot of a travelling wave is shown in figure-1 and a snapshot of a standing wave is shown in figure-2. (Particles are at their respective extremes.The amplitude, frequency, and the speed of both the waves is the same. The string in both the cases is identical). If the energy per unit length of system at point A in figure-1, is x1 and that in figure-2 is x2 . What is value of x1/x2 ?
