Light passes through a pair of very thin parallel slits. The resulting interference pattern is viewed far from the slits at various angles relative to the centerline coming outward from the midpoint between the slits.

The central bright fringe is at = 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

Coherent monochromatic light of wavelength 632.8 nm passes through a pair of thin parallel slits. The figure shows the central portion of the pattern of bright fringes viewed on a screen 1.40 m beyond the slits. What is the distance between the two slits?

A) 0.0703 mm
B) 0.141 mm
C) 0.281 mm
D) 0.562 mm
E) 0.633 mm
