If an object far away from a convex mirror moves towards the mirror, the image also moves. Does it move faster, slower or at the same speed as compared to the object?

slower than the object, as a convex mirror is a diverging mirror , and if I did any mistake please exuce me

The image moves slower as compared to the object.      

Explanation:

  • If the object is far from a convex mirror, the simulated image is similar to the focal point.
  • As the object is moving towards the mirror, the reflection moves backwards towards the mirror.
  • Thus the object travels a greater distance than the image at an equivalent interval of time.
  • So the image is moving slower than the object itself.

The object image moves slower relative to the target. It can be explained using the formula mirror.

                                        $\frac{1}{u}+\frac{1}{v}=\frac{1}{f}

We know the distance of object (u) is positive for a convex mirror, the distance of image (v) is negative, and the focal length is also negative

                                          $\frac{1}{u}-\frac{1}{v}=-\frac{1}{f}

As u = +ve                         $\frac{1}{v}-\frac{1}{f}>0

                                          $\frac{1}{v}>\frac{1}{f}

                                          v > f

Hence the picture is always created within the mirror focal length.

Thus, the distance the image moves is much slower than the distance the object is moving.
