          • The 3rd graph has a different horizontal (time) scale than the 1st and 2nd graphs. The 3rd graph’s time scale is larger (zoomed out) so the wave looked more “squished together” than the waves in 1st and 2nd graphs. DrDaveBilliards did this to show how the amplitude of the combined wave changes. For example, the first demo of 500Hz consists of 500Hz waves in all the top 3 graphs, but the 3rd graph have the wave “squished” because of the different scale.
