please show work You've set up a Michelson interferometer with very slightly crossed output beams of 500nm - wavelength light and are looking at the output fringes vs. position. Unfortunately, someone walks by and breathes near one of the mirrors, moving it by 250nm (about 1/100 the thickness of a human hair). By how much will the fringes move (that is, what fraction of the period of the fringe pattern)?
