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.

Question

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?
(1 point)

• Wave energy increases with frequency and decreases with wavelength.
• Wave energy is directly proportional to the amplitude of the wave.
• The greater the wavelength, the more kinetic energy the wave has.
• Wave energy decreases as the wave moves closer to shore.

Answer 1

The correct statement regarding the relationship between an ocean wave and the energy of that wave is:

• Wave energy is directly proportional to the amplitude of the wave.

This means that as the amplitude (the height of the wave) increases, the energy carried by the wave also increases.
