What is the approximate frequency of a wave with a wavelength of 4.5 meters traveling at a speed of 15 m/s?

To determine the frequency of a wave, we can use the formula:
frequency = wave speed / wavelength.
In this case, the wave speed is given as 15 m/s and the wavelength is 4.5 meters.
frequency = 15 m/s / 4.5 m ≈ 3.33 Hz.
Therefore, the frequency of the wave would be approximately 3.33 Hz.
