as frequency increase, wavelength ______________.

as frequency increase, wavelength ______________.
Answer
Brief Explanations:
The relationship between frequency ($f$) and wavelength ($\lambda$) is given by the formula $c = f\lambda$, where $c$ is the speed of light (a constant in a given medium). Since $c$ is constant, when $f$ increases, $\lambda$ must decrease to maintain the equality.
Answer:
decreases
