Description: Go to curiositystream.com/minutephysics to get access to CuriosityStream AND Nebula (where you can watch the extended version of this video), plus you'll get a 26% discount on an annual subscription. This video is about the "Kelvin wake" shape of water wakes behind boats - we talk about mach angle, dispersion, superposition of many waves, and how these all lead to the pattern of a wake. We don't get into Froude number though...
