The speed of a wave equals its frequency times wavelength. What are the disadvantages of shielding a thermometer? Peak-to-peak (pk-pk) is the difference between the maximum positive and the maximum negative amplitudes of the wave. The wavelength of a wave does not affect the speed at which the wave travels. It also does not affect wave speed. However in the case if the speed of the source is equal to the wave, I think, if there where N wavefronts emitted the amplitude should be N-times larger than that of one amplitude (see This picture from Wikipedia (the case Ma=1)). A wave caused by a disturbance with more energy has greater amplitude. The speed of a wave is only altered by alterations in the properties of the medium through which it travels. Why do waves of depolarization sweep down the length of an axon after only one stimulus? The amplitude carries energy in a wave between specific points, and the frequency is related to the period.
