Mirrors on the outside of the passenger side of cars often contain a message that says something like, "Objects are closer than they appear." In other words, the image seen in the mirror, although looking like the objects in other respects, appear to be further away than they actually are, because the images are smaller than the objects.
What kind of mirror is being used in this case?

The passenger side-view mirror on an automobile often has notation. "Objects seen in the mirror are closer than they appear". Is the image really farther away than the object?

Why is "Objects in mirror are closer than they appear" written on back and side mirrors of a vehicle? [5 MARKS]

Whatever be the position of the object, the image formed by a mirror is virtual, erect and smaller than the object. The mirror then must be : (a) plane (b) concave (c) convex (d) either concave or convex

We wish to obtain an erect image of an object, using a concave mirror of focal length 15 cm. What should be the range of distance of the object from the mirror? What is the nature of the image? Is the image larger or smaller than the object? Draw a ray diagram to show the image formation in this case.
