The wave speed can be calculated using the formula v = λ/T, where λ is the wavelength and T is the period. In this discussion, the wavelength (λ) is determined to be 3 meters, and the period (T) is 4 seconds. Consequently, the wave speed (v) is calculated as 0.75 m/s. This approach effectively utilizes the relationship between wavelength, period, and wave speed to solve the problem.
PREREQUISITESStudents studying physics, particularly those focusing on wave mechanics, as well as educators looking for clear examples of wave speed calculations.

collinsmark said:You've nailed it with your relevant equation. (By that I mean your "v = λ/T" equation is exactly the one you want to use.)
With one of the graphs, you should be able to figure out the wavelength, λ. In other words, answer, "how long is one wavelength?" Still in other words, "how many meters is one period of the wave?"
With the other graph, you should be able to figure out the period of the wave. In other words, answer, "how long does it take (in seconds) for the wave to cycle through one wavelength?" Or, "how many seconds is one period?"
