We know that waves transmit energy. There are many types of waves: light, microwaves, x-rays, sound waves, and ocean waves are all examples of waves transferring energy. Ocean waves are a renewable energy source that uses the energy of the waves to generate electricity.
Consider any ocean wave. What is the relationship between an ocean wave and the energy of that wave?
