here's a good representation of sensor sizes. Imagine that you are using an FX lens but a smaller sensor. The sensor would be getting light from only a portion of the lens.

OK, we're photographing a pinhead placed in the center of our image. Reflected light from the pinhead goes lots of places including the entire surface of the lens on our DX, or any other, camera. So what happens to the light from the pinhead that strikes the edge of the FX lens? Why wouldn't it be refracted right back into the image just as well as the light striking the center of the lens.
