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?
