A real place?
There’s an optics experiment I did, bloody fiddly, where a picture goes through some lenses, and there’s a plane of the frequencies, and it goes through further lenses and is projected on a screen.
By blocking out areas in the frequency plane, you can change the image. It was extremely fiddly so huge thanks to Dr Bruce Sinclair at St Andrew’s.
Physics lab work is where you get to see how things work, although if you go through the theory several months after you’ve done the lab work you’re a bit lost.
