Monochromatic light from a distant source is incident on two parallel narrow slits. After passing through the slits the light strikes a screen, as shown in Figure 24-1.

What will be the nature of the pattern of light observed on the screen?
A) A rainbow of colored lines will be seen spreading out on either side of point O.
B) The screen will be uniformly illuminated except for two dark bands, one in line with each slit.
C) There will be two bright bands of light, one in line with each slit.
D) There will be a series of alternating light and dark bands.
E) The screen will be most brightly illuminated at point O, with the intensity decreasing slowly and uniformly as you move outward from point O.
