Consider an original figure consisting of an arrow pointing towards the top-right corner, with a small solid circle (dot) at its tail end. What will be the water image of this figure if the water surface is located horizontally just below it?

When an object forms a water image, it undergoes a strict vertical inversion (top becomes bottom, and bottom becomes top), while the horizontal orientation (left and right sides) remains unchanged.
* The original arrow points towards the top-right.
* Vertically flipping the top component changes it to bottom, while the right direction remains unchanged. Thus, the arrow points towards the bottom-right.
* The dot is at the tail end (bottom-left of the arrow line). Flipping it vertically moves it to the top-left relative to the inverted line, maintaining its position at the tail end of the arrow.

Therefore, the water image is an arrow pointing towards the bottom-right corner with a dot at its tail end.
