Question

as frequency decreases, wavelength _____________.

type

wavelength

frequency

uses

Explanation:

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 vacuum). When $c$ is constant, if $f$ decreases, $\lambda$ must increase to maintain the equality.

Answer:

increases
