Light from a sodium vapor lamp passes through a filter that blocks all but a single narrow wavelength band. It then fallson two slits separated by 0.460mm. The resulting interferencepattern on a screen 2.20 meters away has adjacent bright fringes separated by 2.82 mm.
a) What is the wavelength of the light?b) If the slit separation were narrowed to 0.35 mm, what is theseparation of the fringes?
