Two slits separated by a distance of d = 0.120 mm are located at a distance of D = 770. mm from a screen. The screen is oriented parallel to the plane of the slits. The slits are illuminated by a coherent light source with a wavelength of λ = 537 × 10-6 mm. The interference pattern shows a peak at the center of the screen (m = 0) and then alternating minima and maxima. a) What is the path length difference between the two waves from the two slits at the first (m = 1) maximum on the screen? b) What is the path length difference between the two waves from the two slits at the first (m = 0) minimum on the screen? c) Calculate the distance on the screen between the central maximum (m = 0) and the first (m = 1) maximum (You can assume sin(θ) ≈ tan(θ) ≈ θ, with θ expressed in radians).
