Question

If frequency increases, then wavelength _________.

Answer 1

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.

Step-by-step explanation:

Answer 2

decreases

Explanation

Frequency and wavelength are inversely proportional to each other. And if wavelength increases, its frequency decreases.
