Question

Where would the image be formed by a convex mirror if the object is placed: 

 at infinity? 

Draw labelled ray-diagrams to show the formation of image in both the case.

Answer 1

at infinity 

 

The image will be virtual, diminished and behind the mirror when the object is at infinity.
