When the tuning fork was sounding, what happened to the ball once it was brought into contact with the tuning fork?
The ball moved away from the tide
What were the prongs doing in order to produce the sound you heard?

What do you notice about the water surface in each case?
The water moves- there were ripples and splashes. A ripple is a small wave.
Which wave delivered more energy, the low amplitude or high amplitude wave?
The high amplitude wave
The greater the _______ of the wave, the more ______ it transfers.
Amplitude, energy
