If a 4.5-meter wave traveled at a speed of 15 m/s, what would its frequency be?

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.
