If the frequency of a wave is kept constant and the amplitude increases will the wavelength increase or remain constant?

The wavelength will remain constant.

Explanation:

lambdaλ (wavelength), ff (frequency), and vv (speed) for a wave are related by v=lambdafv=λf. Note how nothing in this equation depends on amplitude. Therefore, assuming a constant speed, if the frequency is constant then the wavelength is too, regardless of changes to the amplitude.
