Asked by Zephyr Benedict

A buoy bobs up and down in the ocean. The waves have a wavelength of 2.5 meters, and they pass the buoy at a speed of 4.0 meters/second. What is the frequency of the waves?
Note: frequency (Hz) = wave speed (m/s) / wavelength (m)
A. 1.6 Hertz
B. 10 Hertz
C. 7.5 Hertz
D. 4 Hertz

Use f = v/λ. f = 4.0 m/s ÷ 2.5 m = 1.6 s⁻¹ = 1.6 Hz.

Answer: A. 1.6 Hertz.
