Answer: Yes, it is true.
Step-by-step explanation:
The given statement is true, as in the standing wave there is no transmission of energy because the total or overall energy of the wave is basically given by the amplitude and frequency of the standing wave which is constant.
In the standing wave, the amount of the energy are equal at each point so that is why the energy is not being transferred. The standing wave are basically composed of the two travelling wave that carry energy in the opposite direction and it is also associate with the resonance.
