Can You Build a Michelson Interferometer on a Budget?

AI Thread Summary
Building an interferometer, akin to the Michelson experiment, is a viable project to demonstrate the constant speed of light in a vacuum. A suggested resource for constructing a simple Michelson interferometer for under $150 is provided through a link to a lesson from LIGO. This project can effectively illustrate fundamental principles of physics and light behavior. Participants in the discussion are encouraged to explore various references and resources to aid in their construction efforts. Engaging with these materials can enhance understanding and execution of the project.

I have been thinking about building an interferometer (similar to the Albert-Michelson experiment)for my physics project to prove that the speed of light in vacuum is always constant.

Are there any references that I can relate to building an interferometer?

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
