a skipper on a boat notices wave crests passing the anchor chain every 5 seconds. the skipper estimates the distance between crests is 15 m. what is the speed of the water waves? a. 3 m/s b. 5 m/s c. 15 m/s d. 45 m/s

Sagot :

The speed of the water waves is 3 m/s.

The wave speed is the distance a wave travels in a specific amount of time, such as the number of meters it travels in a second. The formula to calculate wave speed is given as V = f×λ. V is the speed or velocity in m/s, f is the frequency in hertz (Hz), and λ is wavelength in m.

Here, given the time period (T) is 5 s and the wavelength is 15 m.

First, the frequency can be calculated using the formula, f = 1/T.

f=1/5=0.2

Then, the wave speed is,

V=0.2×15=3 m/s

The answer is 3m/s.
