Think a Michelson interferometer operated by light from a sodium lamp with λNa = 589 nm. Suppose the interferometer is utilized to check the accuracy of a meter stick by moving one of the mirrors a distance of precisely 1.87 m (as determined with the meter stick) and counting bright fringes as they appear at the detector. How many bright fringes will be observed while the mirror is being moved?
