A tall tree is growing across a river from you. You would liketo know the distance between yourself and the tree,as well as itsheight, but are unable to make the measurements directly. However,by using a mirror to form an image of the tree and then measuringthe image distance and the image height, you can calculate thedistance to the tree as well as its height. Suppose that thismirror produces an image of the sun, and the image is located0.8610 m from the mirror. The same mirror is then used to producean image of the tree. The image of the tree is 0.9902 m from themirror. (a) How far away is the tree? (b) The imageheight of the tree has a magnitude of 0.20 m. How tall is thetree?
