Monochromatic light from a distant source is incident on two parallel narrow slits. After passing through the slits the light strikes a screen.

A series of alternating light and dark bands.* C. A rainbow of colored lines will be seen spreading out on either side of the center. D. Two bright bands of light, one in line with each slit. E. The screen will be uniformly illuminated except for two dark bands, one in line with each slit.
