Have you ever looked at a window from outside and thought, “Why does everything reflected in it look wavy messed up… but I can still see through it just fine?”
Turns out there’s some really cool physics behind that.
This video explains the Wavy Window Paradox and why light passing through glass behaves very differently from light reflecting off it. It all comes down to the symmetry of Snell’s Law and it’s a surprisingly clever bit of physics hiding in something we usually barely think about.
After watching this, you’ll probably never look at a window quite the same way again.
