Harmonic light waves are emitted by a source equidistantbetween two narrow vertical slits 0.25 mm apart in a screen. The light waves detected at a screen parallel to the screencontaining the slits but 44 cm away have the usual maximun at thepoint opposite the midpoint of the two slits, and the first minimumoccurs at a point 0.64 mm from the maximum. What is the wavelength of the light?
