Understand the Problem

The question is asking about the function or application of Michelson's interferometer, which is a scientific instrument used to measure light interference patterns.

More Information

The Michelson interferometer, invented by Albert A. Michelson, is a crucial component in optical interferometry. It splits a light beam into two paths, then recombines them to measure variations caused by optical properties or surface irregularities.

Tips

A common mistake is confusing the mechanisms by which interferometers function—for Michelson, it involves splitting and recombining light beams using mirrors and beamsplitters.
