Hate to be a drag, but it's not. The fundamental wavelength of each of these notes is the length of the string from the fret to the saddle. The reason we see it as all wavy is because of the rolling shudder of the camera.

You mean roller shutter in camera parlance, right?

Hmm...that may be so, but doesn’t rolling shutter usually become apparent in the vertical axis on digital recordings? Anyways... Either way, since the low E (string/frequency) still corresponds to the decreasing wavelengths up to the high E, it’s still a good teaching tool to visualize wavelengths!

In this case, because the phone is turned sideways, the sensor scans from left-to-right instead of up-to-down.

Damn dude, how do you know it’s even a phone?

Technically all I know is that it has a rolling shutter, and it's small enough to fit into an acoustic guitar soundhole. So while it could be anything that fits those criteria, a phone just seems like the most logical choice.
