Question

You are about to dive into a pool, but stop near the edge when you notice a 1 meter alligator at the bottom. If the pool is 2 meters deep and the alligator is at a 30 degree angle, how long does the alligator appear to be to you standing above the surface of the pool? Does the alligator appear to be deeper or shallower than it really is? Can the alligator see you?

Is there a way you can draw out the diagram so that I can visually see it?

Answer 1

The alligator is at an angle of 30° vertically from height of pool. Above the surface of pool an observer observes it at 1m from the pool depth.

So, alligator cannot see a person standing on above the pool.
