## Homework Statement

Okay, here is a photo of the wave I did on a graphing program: http://img221.imageshack.us/i/wavelengthsgraph.jpg/

Now the total distance the wave travels is 4.8 M. There are 3 crests and 3 troughs, but there is only 2 wavelengths throughout the wave. This confuses me.

## Homework Equations

To finding the wavelength is it 4.8/2? Or 4.8 divided by 3?

## The Attempt at a Solution

I tried 4.8/3, but I didn't feel to comfortable with the answer since the wavelengths do not seem to be 1.6 M long, so would it become 4.8/2=2.4M?

And how would I know how to determine the answer for future equations? Thanks in advance.
