When Theory Meets Reality: The Double-Slit Disappointment

When Theory Meets Reality: The Double-Slit Disappointment

What we're witnessing here is the classic double-slit experiment going rogue in someone's DIY setup. The yellow filter is supposed to show wave interference patterns, but instead we're getting... whatever this blurry mess is. Textbooks vs. reality, folks! Thirty years of teaching physics and I still can't get undergraduate lab equipment to demonstrate what's in the lecture slides. Next time a student asks "will this be on the exam?" I'll just show them this image and say "only if you can explain why your experiment looks nothing like the theory."
