1. If a wave has a wave height of 5 meters, in what depth of water would it begin to break?

2. In what depth of water would a wave begin to break if it had a wave height of 3 meters?

3. According to the diagram, how far from shore would a wave break if it had a wave height of 3 meters

4. How high must a wave be to break in water that is 7.8 meters deep?

5. If the wind picked up and caused an increase in wave height, would wave break farther from shore or closer to shore? Why?
