Asked by Zephyr Benedict
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?
A. Wave energy increases with frequency and decreases with wavelength.
B. Wave energy is directly proportional to the amplitude of the wave.
C. The greater the wavelength, the more kinetic energy the wave has.
D. Wave energy decreases as the wave moves closer to shore.

Answer: B.
Explanation: For ocean (mechanical) waves the energy is strongly tied to the wave amplitude — in linear wave theory the total energy per unit surface area (potential + kinetic) is proportional to the square of the amplitude (E ∝ A^2). The other choices are incorrect: A describes photons, not ocean waves; C is not generally true (wavelength affects group velocity and power transport, but energy depends on amplitude); D is not generally true (shoaling can increase wave height and energy density near shore, though breaking and friction eventually dissipate energy).
