Based on the data table, if there is 6 units of amplitude, what would you expect the energy to be? Explain.

• Less than 18 units because as amplitude increases, energy decreases

• Less than 50 units because as amplitude increases, energy decreases

• Equal to 50 units because amplitude and energy remain constant

• More than 50 units because as amplitude increases, energy increases

The graph on the left shows the relationship between wave amplitude and wave energy. How does the wave’s energy change as the wave’s amplitude changes?

• They are indirectly proportional. As energy increases, the amplitude decreases.

• They are directly proportional. As the energy increases, the amplitude decreases.

• They are indirectly proportional. As the energy increases, the amplitude increases.

• They are directly proportional. As the energy increases, the amplitude increases.
