If you're programming a game where a boat moves through water, you might be tempted (as I would) to change the V-shape angle of the waves behind the boat based on how fast the boat was moving!
What if I told you that that V-shaped angle is always 19.47°, regardless of how fast the boat is travelling? 😱
This pattern even holds true for a duck traversing a pond. 🦆
The envelope of these waves stands at a fixed angle, and the wake has a characteristic feathered pattern.
