If a wave is traveling at a certain speed and its frequency is doubled, what happens to the wavelength of that wave?

the wavelength will decrease: half of its length

Explanation: The wave speed id expressed in the product of frequency and wavelength. For wavelength it is inversely proportional to frequency so if the frequency is doubled the wavelength decrease to half of its length or distance.
