SOLUTION: You observed an anchored boat rise and fall every 8.9 seconds as waves whose crests are 19 meters apart pass by it. what is the frequency of the observed waves?

Question 1191558: You observed an anchored boat rise and fall every 8.9 seconds as waves whose crests are 19 meters apart pass by it. what is the frequency of the observed waves?
Answer by math_tutor2020(3817) (Show Source): You can put this solution on YOUR website!

Period = 8.9 seconds per 1 cycle
Frequency = 1/period
Frequency = 1/8.9
Frequency = 0.1123596 cycles per second approximately

The info about the wavelength (the 19 meters) is irrelevant info that your teacher probably put in there as a distraction.
