Yellow light of wavelength 589nm is used to illuminate a double-slit system, resulting in the formation of an interference pattern on a screen that is located 2.00m away from the slits. If successive interference maxima have a separation of 2.50 cm on the screen, find the slit separation.

One half travels through glass(n=1.52), and the other half travels through an equivalent length ofwater(n=1.33). What is the minimum path length L that is required to put the two waves exactly in phase again?
