Answer:
When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases, wavelength decreases. The opposite is also true— as frequency decreases, wavelength increases.
Step-by-step explanation:
The number of complete wavelengths in a given unit of time is called frequency. As a wavelength increases in size, its frequency and energy decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
