This is the infamous "Diffraction vs. Interference" meme that separates the physics enthusiasts from the mortals. The top panel shows a single slit diffraction pattern, while the bottom shows the double-slit interference pattern that made quantum physicists question reality itself. If you're looking at this thinking "it's just some lines," congratulations – you're living in blissful ignorance! Meanwhile, physics students are having existential crises because these patterns proved light behaves as both a wave AND a particle. The double-slit experiment is basically the physics equivalent of finding out Santa isn't real, but WAY more traumatizing. Welcome to the club where particles don't follow the rules and everything you thought you knew about reality is a lie!
