How do you find frequency given this wave graph?

How do you find wavelength given this wave graph? [ignore my title please]

Homework Equations

c= (wavelength)(frequency)

The Attempt at a Solution

I always see displacement (y) vs distance (x) graph, but this one is displacement (x) vs t

I'm kinda confused how you solve for the wavelength

can someone help me with interpreting this graph?

I know the question is asking for frequency, but is it possible to figure out the wavelength given this graph?

The problem asks the frequency. You get the wavelength if you know the speed of the wave in that medium, but it is not given.

You can't solve for wavelength.

The particle moves back and forth periodically. What's the period of that motion?

I got the answer.
1 wave is 0.05 sec

frequency is the the number of cycles per sec
so here 1 cycle / 0.05 sec
so 1 sec/ 0.05 = 20

What units ?
