Problem
An artist wants to paint a landscape while remaining hidden behind a wall. She constructs a simple periscope using two plane mirrors, each inclined at 45° to the horizontal. The mirrors are separated by a vertical distance of h=80cm. She positions her eye d=25cm horizontally away from the lower mirror. When she looks through the periscope, she can see a tree that appears to be directly in front of her. If the tree is actually located D=12m horizontally from the upper mirror, what is the total distance traveled by light from the tree to her eye?
