Question
What is the advantage of using a polygonal mirror with larger number of faces in Michelson method of measuring the speed of light?
✓

Answer

The advantage of using a polygonal mirror with larger number of faces in the Michelson method is it gives the value that is very near to the accurate value and minimises the error.
