Answered by PrincessesPrince

Answer:

One fringe is equal to one wavelength. If there is only one mirror then moving the mirror 5mm is altering the path length by the same amount. (I presume this is only affecting one of the two beams of light if you’re having 2000 fringes shift past your mark)

5 Million nm / 2000 = 2500 nm
