Question

lesson 26 - waves
as frequency decreases, wavelength

Explanation:

The relationship between wave frequency ($f$), wavelength ($\lambda$), and wave speed ($v$) is given by $v = f\lambda$. For a wave in a fixed medium, wave speed $v$ is constant. Rearranging gives $\lambda = \frac{v}{f}$, so wavelength is inversely proportional to frequency. Thus, if frequency decreases, wavelength increases.

Answer:

increases
