2. Stressed out by a physics assignment, you head to the beach to relax. Once you are there, you watch the waves crash into the shore. You count that 15 waves crash into shore in 1 minute. a. Calculate the frequency of the waves. b. Calculate the period of the waves. c. If there is a distance of 6m between each wave crest, calculate the wave speed. d. At the next beach over, you see that the waves have a smaller amplitude, but the same frequency and wavelength. Which waves would reach the shore faster: the small amplitude waves, or the large amplitude waves? e. Since you can't get your mind off of physics, you begin to think about how sound travels. You recall that sound travels faster in water than air. Use particle theory to briefly explain why
