What is amplitude?

• The distance from the center line ( or the still position) of a waveto the top of a crest or to the bottom of a trough.

• The number of waves passing a point in a certain time.

The highest point on a wave is:

• the crest

• the trough

• the top

• the coast

What is the relationship between amplitude and energy?

• As amplitude increases, energy increases

• As amplitude decreases, energy increases

• The relationship in inversely proportional to each other.

• There is no relationship between amplitude and energy
