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) I0 cos 15°
E) I0 cos2 15°
