Final answer:
The wave speed can be calculated using the formula: wave speed = wavelength × frequency. In this case, the wave speed is 5 m/s.
Step-by-step explanation:
The wave speed can be calculated using the formula: wave speed = wavelength × frequency. In this case, the wavelength is given as 10 meters and the time it takes for a crest to move past is 2 seconds. To find the frequency, we can divide the wavelength by the period, which is the time for one complete wave to pass. In this case, the period is 2 seconds since a crest moves past every 2 seconds.
Therefore, the frequency is 1 wave per 2 seconds or 0.5 waves per second. Now, we can substitute the values into the wave speed formula:
Wave speed = 10 m × 0.5 waves/s = 5 m/s
