Rear view mirrors of cars carry a warning message "objects in the rear view mirror are closer than they appear. Why?

Open in App

Solution

Rear view mirrors of cars are convex in nature. When a ray of light falls on a convex mirror, it gets converged and meets at a point. The resultant image is real and diminished. Though the images appear to be far away in the mirror, they will actually be nearer. Hence, rear view mirrors of cars carry a warning message stating that "objects in the rear view mirror are closer than they appear".
