$A$ convex mirror has a focal length $f$. $A$ real object is placed at a distance $f$ in front of it from the pole. The image is produced at:

$A$ mobile phone lies along the principal axis of a concave mirror,as shown in the figure. Show by a suitable diagram,the formation of its image. Explain why the magnification is not uniform. Will the distortion of the image depend on the location of the phone with respect to the mirror?

$A$ convex mirror of focal length $f$ forms an image which is $\frac{1}{n}$ times the size of the object. The distance of the object from the mirror is

$A$ square cardboard of side $3\, cm$ is placed $25\, cm$ from a concave mirror of focal length $10\, cm$. What is the area enclosed by the image of the cardboard? (The plane of the cardboard is perpendicular to the principal axis.)

An object is placed at the principal focus of a convex mirror. The image will be at

An object $O$ is placed at $7 \,cm$ to the left of a concave mirror of radius of curvature $12 \,cm$ as shown in the figure. The position of the image will be at a distance of
