Andrea asked her brother to take a 4 ft floating raft out of the water near the wave-swept shore. Using this raft as a measuring tool, she estimated that the wavelengths of these particular ocean waves were about 11 ft.

How fast are these surface ocean waves if the frequency remains 16 Hz?

Answer in units of ft/s.

176ft/s

Explanation:

Speed of a wave is a function of the frequency and wavelength of the wave. It is expressed mathematically as:

V = fλ where:

V is the speed of the wave

f is the frequency

λ is the wavelength

Given f = 16Hz, λ = 11ft

V = 16*11

V = 176ft/s
