1) Is the relationship between energy and amplitude linear or nonlinear? How can you tell?

2) What does it mean to be proportional rather than equal?

3) How is a wave's energy affected if its amplitude is doubled?

4) A wave's amplitude is halved. How does this affect its energy?

5) Wave A has an amplitude of 1 unit. Wave B has an amplitude of 5 units. How does the energy of the two waves compare?

"Mathematical models are helpful in understanding the properties of waves. The relationship between energy and amplitude is shown in this graph. This means that the energy of a wave is proportional to the square of its amplitude. This relationship is shown on the graph. Study the graph and apply your understanding of waves and mathematical relationships to answer the questions below. "
