Amplitude relation with periodic time

[SakuRERE]

Homework Statement

Ql: Which sound wave will have its crests farther apart from each other - a wave with frequency 100 Hz or a wave with frequency 500 Hz?

Homework Equations

Frequency= 1/ periodic time

The Attempt at a Solution

I did it like that:
I just found the periodic time for each wave, substituting in the previous relation. and I ended up with :
first wave (500Hz) => 0.002 s
second wave (100 Hz) => 0.01 s

which means that the second has larger wavelength making it ~slower (if we can say), and the first one with a larger wavelength.
however, I still can't reach the crest (amplitude) using the given information!

is there any relation between the periodic time and the amplitude?
or the wavelength and the amplitude?

thanks in advance

I read the question's use of "farther apart" as relating to distance. You would then need an equation that involves some sort of length.

You ask about amplitude there in what I quoted and in your thread title, but it is not in the problem statement as far as I can see. Is there more to the problem statement?

Look in your textbook for the equation that relates a waves velocity, frequency and wavelength.
