In a double-slit experiment, light and dark regions are observed on a screen. What causes a dark region to be observed between two brighter regions? Group of answer choices Light from the two slits undergoes destructive interference. Light from the two slits undergoes constructive interference. The screen is inhomogeneous and absorbs light non-uniformly. It is the shadow cast from the material in which the two slits have been made. The two slits act like polarizing material and some of the...
