IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / â¦ 2). 6 people found this useful. Al Cohen.
The wavelength decreases as the frequency increases. From the universal wave equation velocity = wavelength * frequency, it can be derived that wavelength = velocity / frequenâ¦cy, and therefore wavelength is inversely related to frequency. For inverse relationships, when one variable increases, the other decreases.
