The element sodium can emit light at two wavelengths, 1 = 589.10 nm and 2 = 589.59

Question:

The element sodium can emit light at two wavelengths, λ1 = 589.10 nm and λ2 = 589.59 nm. Light from sodium is being used in a Michelson interferometer (Figure). Through what distance must mirror M2 be moved if the shift in the fringe pattern for one wavelength is to be 1.00fringe more than the shift in the fringe pattern for the other wavelength?
