One microscope slide is placed on top of another with their left edges is contact and a human air under the right edge of the upper slide. As a result the wedge of air exist between the slides?

And interference pattern results when monochromatic light is incident on the edge. And what appears on the left edges of the slides? 1) a dark fringe 2) a bright fringe 3) impossible to determine Which one of the three?
