SUMMARY

This discussion centers on constructing a Michelson Interferometer for educational purposes, specifically to demonstrate the constant speed of light in a vacuum. The original poster, Hyperreality, seeks references for building an interferometer on a budget. A recommended resource is provided, detailing how to build a simple Michelson Interferometer for under $150, which can be found at the LIGO website.

PREREQUISITES
  • Understanding of basic optics principles
  • Familiarity with interferometry concepts
  • Basic physics knowledge regarding the speed of light
  • Ability to follow DIY project instructions
NEXT STEPS
  • Research the principles of interferometry in depth
  • Explore the LIGO website for additional educational resources
  • Learn about the components required for building optical devices
  • Investigate alternative designs for budget-friendly interferometers
USEFUL FOR

Students in physics, educators looking for hands-on experiments, hobbyists interested in optics, and anyone aiming to demonstrate fundamental principles of light and interference.

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?
