When the water waves go through one wide slit (slit wider than wave length), there's no fringes, the water waves spread all over the sides, like in this pic:

or in this pic: http://philschatz.com/physics-book/resources/Figure_28_02_06a.jpg
But when light waves goes through a wide slit, it's split into multiple sides, there are fringes between them, it's not spread equally all over the place, like in this simulation (if you take width of the slit to 3000-5000 nm):

Why there are no gaps when water waves go through a wide slit, but there are gaps when light waves go through a wide slit?
