Explanation:
The image of the object moves slower compared to the object. It can be explained using the mirror formula :1u+1v=1f
We know that for a convex mirror, the object distance (u) is positive, image distance (v) is negative and the focal length (f) is also negative. Thus mirror formula of a convex mirror is:1u−1v=−1f
As u = +ve
1v−1f>01v>1fv<f
Therefore, the image is always formed within the focal length of the mirror. Thus, the distance moved by the image is much slower than the distance moved by the object.
