The 17 second cycle wave has a SECOND wave in it.
Physicsfags/ wave theoryfags.
The first Pic is the one we are used to seeing, but look deeper into it and a SECOND wave form is there.
The graph measure 3 things: 1. frequency, 2. time and 3. amplitude. It is the amplitude (or strength of signal) that is creating this second wave. Can't wrap my mind around this yet. Need thoughts stronger then mine. Anyone?
