Now that you have learned about wave types, complete the following activity.

waves in the ocean

Do the following problems, sketching and writing your answers.

1. The crest of an ocean wave that has an amplitude of 1 meter intersects another wave crest with an amplitude of .75 meter. What is the resulting amplitude? Sketch this and show your calculations.

2. The crest of a wave with an amplitude of 2 meters intersects the trough of a wave with an amplitude of 1.3 meters. What is the resulting amplitude?
