Which expression represents the relationship between frequency and wavelength as described?

Explanation:
When a wave travels at a fixed speed, frequency and wavelength are inversely related. The product of frequency and wavelength equals the wave speed (fλ = v). If the problem uses units where that speed is set to 1, then frequency simplifies to f = 1/λ. This directly expresses the inverse relationship: as wavelength grows, frequency shrinks, and vice versa. The other forms would imply direct proportionality or require a different constant, so they don’t capture the described relationship as cleanly.
