Answer
decreases
Explanation
Frequency and wavelength are inversely proportional to each other. And if wavelength increases, its frequency decreases.
Answer:
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
