So I'm really interested in the field of wave optics, and luckily for my undergraduate program, we get to do a measurement project on any area of our choosing. I was looking up topics and there are some interesting ones such as the luminous fountain where they use the idea of fiber optics to illuminate a stream of water. I'm sort of thinking about incorporating some interference of magnetic fields or sound waves, perhaps even duplicating an apparatus such as the Michelson interferometer. But right now all I have is just a jumble of ideas and no direction. I need to actually perform an experiment that will give me quantitative results that can be statistically analyzed and then interpreted for any practical implications. Any ideas for possible measurements I can make?
