A double slit aperture is illuminated with HeNe laser light (λ = 638 nm). The pattern observed on a screen placed 2.5 m from the aperture is shown in the attached picture. If the distance between the 2nd order minima on either side of the central bright spot is 25 cm, determine the spacing between the slits. (Hint: carefully determine m for 2nd order minima). The spacing between the slits is how many meters? (3 significant figures) Thank you.
