Maria was watching the waves as they hit the boats in the bay. She noticed that they made a complete up and down vibration cycle in 8 seconds. The boats where 20 meters apart, and when one boat was at a high position, the other was at a low. Find the wavelength, the frequency and the speed of the waves
Solve the following problem
1. Frequency
f = nt = 18 = 0.125 Hz
2. Wavelength
λ2 = 20. λ = 40m
3. Speed
v = fλ = (.125)(40) = 5m/s
