What happens if one of the slits, say S1, in Young’s Double Slit Experiment is covered with a glass plate which absorbs half the intensity of light from it?

The bright fringes become less-bright and the dark fringes have a finite light intensity The bright fringes become brighter and the dark fringes become darker The fringe width decreases No fringes will be observed
