Please help I have been stuck on these homework question for a long time!!

a)

\fFrequency refers to the amount that one waveform is displaced along the x-axis from an otherwise identical waveform. Wavelength is the maximum distance a vibrating particle moves from its equilibrium point. The frequency of the wave is the same as the frequency of the vibrating source. Wave speed is determined by the frequency and the wavelength of the wave.\fa dog jumping up and down while his collar is attached to a spike in the ground a guitar string the snapping of a whip two children holding the ends of a jump rope while they wiggle it
