They are unusually regular. Look at the spaces between pulses (Frequency/Wave period).
Agree they vary quite a bit in peak amplitude( distance up & down from the horizontal center in layman's terms).
Mo info:
1. Peak amplitude
2. Peak-to-peak amplitude
3. Root mean square amplitude
4. Wave period (not an amplitude)
Can you explain what the deal is about this wave and how it changed the world. I am not understanding it. Thanks.
Maybe related to Qs watch the water drops? Water has waves.
I think I understand now. Thanks a lot for your very clear explanation and graphic.
