The Michelson?Morley interferometer is an important and challenging experiment in many undergraduate
as well as post-graduate physics laboratories. The apparatus required for this experiment is costly
and delicate to handle. It also requires considerable skill to obtain a set of sharp fringes. This
frontline presents a low cost (~US$50) design of the experiment, which can be easily fabricated in
any undergraduate laboratory. It is easy to handle as well as any part of this set up being easily
replaced in case of any damage.
