Wavelength is ______ to frequency.

Explanation:
Wavelength and frequency are linked through the wave’s speed: the speed equals wavelength times frequency. In a fixed medium, that speed is constant, so changing the frequency forces the wavelength to change in the opposite direction. Put simply, λ = v/f (or c/f for light in vacuum). If frequency doubles, wavelength halves. The other ideas would imply a direct increase, no relation, or equality, which contradicts the constant speed relationship.
