Answer

Explanation:

Step1: Recall wave - frequency relationship

The speed of sound $v$ in a given medium is constant. The relationship between speed $v$, frequency $f$, and wavelength $\lambda$ is $v = f\lambda$.

Step2: Analyze the effect of frequency on wavelength

Since $v$ is constant, $\lambda=\frac{v}{f}$. A lower - frequency wave has a longer wavelength and a higher - frequency wave has a shorter wavelength. The bell has a low frequency and the siren has a high frequency. So, the sound wave produced by the bell has a longer wavelength than the sound wave produced by the siren.

Answer:

The sound wave produced by the bell has a longer wavelength than the sound wave produced by the siren.
