Question 4: Is there a transfer of energy through a medium when a stationary wave is produced in it? Explain.
No, this is not possible to transfer energy through a medium when a stationary wave is produced in it.
Transfer of energy in a stationary wave would take place when the wave pattern (nodes and anti-nodes) were moving particle to particle. As we know that in case of stationary waves, the node points are at rest so that whole of the wave is stationary. Therefore, energy cannot be transferred through a medium by a standing wave. The waves don’t move in any direction and the energy is not transferred.
