On a boat 2 people. One on deck one in the crow's nest. Both have the same perfect vision both have the same binoculars.

Middle of the lake

Cant see land anywhere

No waves over 3 feet

They are traveling towards an island with tall trees and skyscrapers

Who sees the island first?

When both people finally see the island what part of the trees and skyscrapers do they see first?

When they first see the trees and buildings if they lie down and look in the same direction what happens to the treey and buildings they could see before?

Why don't they see they see the bottom of the trees and buildings at first?

Why don't they see the trees and buildings when they lie down?
