SUMMARY
The discussion focuses on the construction and testing of a Michelson interferometer, specifically addressing the effects of misaligning one of the outer mirrors by a small angle (theta) on the resulting interference pattern. Participants emphasize that misalignment alters the shape of the interference pattern observed on the detector plane, and this pattern changes dynamically as the other mirror is adjusted. The conversation encourages hands-on experimentation using accessible materials such as a laser source, a beamsplitter, first surface mirrors, and a white paper screen to build a functional interferometer.
