Standing waves propagate on a rope with 1.27 grams/meter of rope length density. That rope is used for melde experimental set-up. A 40-gram load is tied and hung on a rope end which is passed on a pulley. If it is known that earth free-fall acceleration on this experiment lab is 9.78 m/s^2, the used rope length is 75 cm, and these are two wave maxima and a minimum on a rope. Determine the amount of propagated energy due to the standing waves. The standing waves amplitude is 0.5 cm.
