Two slits separated by a distance of d = 0.12 mm are located at a distance of L = 760 mm from a screen. The screen is oriented parallel to the plane of the slits. The slits are illuminated by light of wavelength λ = 520 nm. The interference pattern shows a peak at the center of the screen (m = 0) and then alternating minima and maxima. What is the path difference between the waves from the two slits at the first (m = 0) intensity minima on the screen? Report your answer in units of nm.
