Wave-particle duality strikes again! The left shows light behaving like a nice, orderly particle giving us a clear image. The right shows the same scene but with light throwing a quantum tantrum as a wave—all blurry and refusing to sit still for the photo.
It's like light has two personalities: the professional "I'll help you see things clearly" particle mode versus the chaotic "I'm just gonna spread myself everywhere" wave mode. Next time someone takes a blurry photo of you, just blame quantum physics!
