A convex mirror, like the passenger-side rearview mirror on acar, has a focal length of -2.0 m . An object is 4.0 m from themirror. Use ray tracing to determine the location of its image. Howfar is the image from the mirror? Input positive value if the imageis on the same side from the mirror as an object and negative ifthe image is on the other side. Is the image upright or inverted?Is it real or virtual?
