Question

What type of image is obtained while using convex mirror when the object is far away from mirror?

Answer 1

Convex mirrors are shaped like a sphere of a circle. Light rays that hit the mirror from far away are scattered all over.

There is a virtual focal point other than the actual focal point on the other side of the mirror.

Hence the image of an object that far away looks upright, formed behind the mirror and is virtual.

Answer 2

Object is at far away from convex mirror so we can say that object is at $\textbf{infinite}$.

So, image will be virtual, erect and highly diminished.

Image will form at focus.
