Final answer:
The inverse proportionality describes the relationship between frequency and wavelength.
Step-by-step explanation:
The name of the pattern that describes the relationship between frequency and wavelength is the inverse proportionality. As the wavelength of a wave increases, its frequency decreases. This is illustrated in the electromagnetic spectrum, where different colors of visible light have specific frequencies and wavelengths associated with them. It's important to note that frequency and wavelength are inversely related.
