Where should an object be placed in front of a convex lens to obtain a real and inverted image of the same size as the object?

The distance between the object kept at $2 \, m$ from a plane mirror and its image is $.....$ (in $, m$)

An object,$4.0 \, cm$ in size,is placed $25.0 \, cm$ in front of a concave mirror of focal length $15.0 \, cm$. At what distance from the mirror should a screen be placed in order to obtain a sharp image? Find the nature and the size of the image.

The figure below shows an object $AB$ placed on the principal axis of a convex lens placed in air. $F_{1}$ and $F_{2}$ are the two foci of the lens. Copy the diagram.
$(i)$ Draw a ray of light starting from $B$ and passing through $O$. Show the same ray after refraction by the lens.
$(ii)$ Draw another ray from $B$ which passes through $F_{2}$ after refraction by the lens.
$(iii)$ Locate the final image formed.
$(iv)$ Is the image real or virtual?

In the case of a convex mirror,if the object is moved away from the surface of the mirror,how do the position and size of the image change?

The laws of reflection are true only for plane mirrors and not for curved mirrors.
