A convex mirror has a focal length of magnitude 6.41 cm. If the image is virtual, what is the object location for which the magnitude of the image distance is one third the magnitude of the object distance? (Enter distance in cm from the front of the mirror. If the image is real, enter NONE.) Your response differs from the correct answer by more than 10%. Double check your...

To practice Tactics Box 18.5 Ray tracing for a convex mirror. The procedure known as ray tracing is a pictorial method for understanding image formation when lenses or mirrors are used. It consists in locating the image by the use of just three "special rays." The following Tactics Box explains this procedure for the case of a convex mirror. The diagram below shows the situation described in the problem. The focal length of the mirror is labeled f the scale...
