While watching ocean waves at the dock of the bay, Otis notices that 10 waves pass beneath him in 30 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 waves?

wavelegnth=5m
period- 10wave 30sec
1wave Xsec
X=3sec
Frequency=1/T
=1/3
=0.33Hz
V=f.wavelegnth
=0.33Hzx5m
=1.65m.s
