प्रश्न
Upto what maximum distance from the pole the image in a convex mirror can be obtained? what will be the location of object then ?
उत्तर
The image formed by a convex mirror is always between pole and focus. Hence, the maximum distance that can be obtained in convex mirror is the focal length. For this case the object has to be at infinity.
