GRED: Double slit with late divider

Guess the Result of the Experiment of the Day (GRED)

A classic double slit experiment is done with light (photons) that creates an interference pattern on the image screen. The experiment is repeated, except now a thin, black, opaque divider is placed from the slit screen, dividing the two slits, to the image screen. Here is an ASCII schematic:

Code: Select all

                                                            
                               |                             |
     s                         |-----------------------------|
                               |       opaque divider        |

    Photon                   Double                         Image
    Source                    Slit                          Screen
                             Screen
What pattern appears on the image screen?
