An ocean wave has a wavelength of 10m A wave passes by every 2s. What is the speed of the wave? (5m/s)

* **Wave speed (v), wavelength (λ), and period (T) are related by the following formula:** v = λ / T<br /><br />* **We are given:**<br /> * Wavelength (λ) = 10 meters<br /> * Period (T) = 2 seconds (since a wave passes every 2 seconds)<br /><br />* **Substituting the given values into the formula:** v = 10 m / 2 s<br /><br />* **Calculating the wave speed:** v = 5 m/s<br /><br />Therefore, the speed of the wave is $\boxed{5 m/s}$.<br />
