The real image of a tree is magnified -0.085 times by a telescope's primary mirror. If the tree's image forms
35 cm in front of the mirror, what is the distance
between the mirror and the tree? What is the focal
length of the mirror? What is the value for the mirror's
radius of curvature? Is the image virtual or real? Is the
image inverted or upright?
