## 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
