Many are introduced to the idea in high school or college physics, usually being shown something like the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Double-slit_experiment\" target=\"_blank\">double slit experiment<\/a>. Whilst this is a great demonstration of the wave properties of light it&#8217;s not exactly obvious how the constructive and destructive interference actually works. Something like the following video, I feel, gives a far better visual impression of what wave interference and superpositioning does in the real world.<\/p>\n<p><iframe title=\"FloWave Exhibition Video 2014\" width=\"668\" height=\"376\" src=\"https:\/\/www.youtube.com\/embed\/WffR6HrEqTA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<p>The really cool demonstration comes in at about 55 seconds in where they demonstrate a concentric wave singularity, or what they call &#8220;The Spike&#8221;. Basically they make the waves work in such a way that once they meet in the middle they all interfere with each other at just the right point. This results in the rapid formation of a cavity in the middle which is then slammed shut as the waves return to their peak. The resulting geyser flows upward for far longer than you&#8217;d expect it to which is a great demonstration of the power of constructive interference with waves.<\/p>\n<p>FloWave itself was constructed to replicate currents and waves seen in the ocean. This allows companies and researchers to test out their technologies in a controlled environment before they get deployed offshore, potentially saving costly repairs and re-engineering. That means that it&#8217;s mostly used to test out how things respond to various kinds of waves and currents, rather than generating awesome wave spikes that shoot water several stories into the air. Still I&#8217;d love something like this on a smaller scale to do my own demonstrations of wave interference.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Wave interference is a relatively simple scientific concept\u00a0that can be difficult to grasp at first.
