Ocean Wave Investigation Ideas: How does the pier effect waves (reflection/diffraction)? What is the average amplitude of today’s ocean waves? What is the average frequency of today’s ocean waves? What time of day results in the highest frequency of ocean waves? What time of day results in the highest amplitude of ocean waves? How does depth affect the frequency of waves? What is the speed of waves as measured from the pier? How does depth affect the speed of waves? Do water waves consistently carry the same amount of energy? What part of the beach is subject to the highest frequency of waves? What part of the beach is subject to the highest energy (amplitude) waves? Or come up with your own!
