I'd like to see a video showing the experiment with some of the more complex interferometer setups so that it's easier to understand the coherent effect. I've seen series like this before: https://www.youtube.com/playlist?list=PL4E7FAAD67B171EBC https://www.youtube.com/playlist?list=PL4E7FAAD67B171EBC But they never seem to explain cases where the expected outputs are all destructive. I can dig down the reddit hole with lots of interesting ideas and explanations: https://www.reddit.com/r/askscience/comments/2fsol9/where_does_the_energy_go_during_the_destructive/ https://www.reddit.com/r/askscience/comments/2fsol9/where_do... But what I really want to see is a good experiment on video that show the effect.
