Question

A person is looking at the image of a tree in a mirror placed 3.5 m in front of him. Given that the tree is at 0.5 m behind his eyes. Find the distance between the image of the tree and his eyes. What are needed to see an object?

Answer 1

Distance between the person and the mirror = 3.5 m 

Distance between the person and tree (object) = 0.5 m 

The image formed in the mirror = 4 m 

The distance between the image of the tree and his eyes = 4 + 3.5 = 7.5
