1.How does energy transfer by waves differ from energy transer my moving objects?

2.Define amplitude and frequency as they relate to a wave.
[I know amplitude is the height of a wave and frequency is how many wavelegths pass a given point per second]Would that answer the question?

Thanks!

1. Energy transfered from waves might only be absorbed at certain frequencies. I depends upon what kind of "wave" it is. Light and sound waves are very different.

2. Your expnanation is just fine.
