A convex mirror (diverging) has a focal length of magnitude f. An object is placed in front of this 2 mirror at a point f from the face of the mirror. The image will appear O at a distance of 2/5 f from the mirror, virtual, upright and reduced. O 2 f from the mirror, virtual, inverted, and diminished O 1/2 f from the mirror, virtual, upright, inverted and enlarged. O 5/2 f from the mirror, real, inverted, and enlarged. 3f from the mirror, real, upright, and enlarged

Problem 5: A student notices that the image produced from a large concave mirror of a distant skyscraper (h = 129 m) is inverted and the magnitude of the height is h; = 1.46 m tall.
