The picture below shows a Mathematica notebook that solves the first three questions. If you have Mathematica on your computer you can click here to download the same notebook.
Question 4: As the observer moves to the right (closer to the fisherman) the submerged part of the fisherman appears to be less shortened.
Question 5: As the observer moves closer to the surface of the water the submerged part of the fisherman appears to be more shortened.
Question 6: This is the most interesting part of this module. To a fish underwater the fisherman appears to be cut in two pieces. The part of the fisherman above the surface of the water appears to be floating in the air. The screenshot below illustrates this phenomenon.
