Intensity of double-slit pattern: Light passes through a pair of very thin parallel slits. The resulting interference pattern is viewed far from the slits at various angles θ relative to the centerline coming outward from the midpoint between the slits. The central bright fringe is at θ = 0°. If the central bright fringe has intensity I₀, what is the intensity of the next bright fringe on either side of it? A) I₀ B) I₀/ C) I₀/2 D) I₀cos 15° E) I₀cos² 15°
