Not just out of phase but 180 degrees from each other. This -perhaps- are
regions where light (wave) diffracted by one slit is at its maximum peak (+)
and light (wave) diffracted by the other slit not just overlaps the former
but happens to be at its lowest peak (-), the net effect is darkness, light
from one slit canceling out with light from the other slit, weird, eh? This
BTW, is called Destructive Interference.
