To determine the wavelength of a wave, you can use the fundamental wave equation:

\[

\text{Speed} = \text{Wavelength} \times \text{Frequency}

\]

In this case, the speed of the wave is given as 1500 m/s and the frequency is 2500 Hz. Rearranging the wave equation to solve for wavelength gives:

\[

\text{Wavelength} = \frac{\text{Speed}}{\text{Frequency}}

\]

Substituting the known values into this equation provides:

\[

\text{Wavelength} = \frac{1500 \, \text{m/s}}{2500 \, \text{Hz}} = 0.6 \, \text{m}

\]

This calculation shows that when you divide the speed of the wave by the frequency, you arrive at a wavelength of 0.6 meters. Thus, the correct answer aligns with this calculation, confirming that the wavelength is indeed 0.6 m.
