Two coherent narrow slits emitting light...

Two coherent narrow slits emitting light of wavelength `lambda` in the same phase are placed parallel to each other at a small separation of `2lambda`. The light is collected on a screen S which is placed at a distance D(`gtgt lambda`) from the slit `S_1` as shown in figure.
