Question

thanks how does changing of the distance of the object,from a convex mirror ,affect the size and the nature of the image formed by it

Answer 1

A convex mirror always gives a virtual erect and a diminished image.
 if the object is at infinity the image is formed at F and for all other positions the image is formed between P and F .
The size of the image is diminished and is virtual and erect.
For all the positions other than infinity the image size changes but always it is less than the size of the object.
