Question

lesson 26 - waves
as frequency increases, wavelength .

Explanation:

The relationship between wave speed ($v$), frequency ($f$), and wavelength ($\lambda$) is given by $v = f\lambda$. For a constant wave speed (e.g., light in a vacuum or sound in air), frequency and wavelength are inversely proportional. Thus, as frequency increases, wavelength decreases.

Answer:

decreases
