Answer:
The speed of a wave can be calculated using the formula: wave speed = wavelength × frequency.
Given that the wavelength of the ocean wave is 4.3m and the frequency is 0.2 waves per second, we can plug these values into the formula to find the wave speed.
wave speed = 4.3m × 0.2 waves per second
To multiply these values, we multiply the numbers and keep the units:
wave speed = 0.86 m/s
Therefore, the speed of the ocean wave is 0.86 meters per second.
