While watching ocean waves at the dock of the bay, Otis notices that 13 waves pass beneath him in 26 seconds. He also notices that the crests of successive waves exactly coincide with the posts that are 5 meters apart. What are the period, frequency, wavelength, and speed of the ocean wave?

    What do you think? It's pretty easy to figure out from the information provided.

    Remember that wave speed equals frequency time wavelength.

    Period (in seconds) = 1/Frequency (in Hz)
