Doubling the amplitude of a wave will double the amount of energy the wave can transfer.
true or false

Is it true? That's what I think but I am not that good at this sort of thing.

  1. False. The energy of a wave is proportional to the square of the amplitude. So, doubling the amplitude increases the energy four-fold
