The Short Answer

The part of your nail that didn't grow out is firmly "adhered" to the nailbed so it appears translucent because the hydration provided by the nailbed smooths the rough underside like the tape smooths the rough side of frosted glass. If your nails are better hydrated then they dry out slower so sometimes they might still be transparent immediately after growing out (the same way the tip of your hair tend to be drier than the root).
