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

Explanation

The formation of the image of the phone is shown in figure. The image of the part which is on the plane perpendicular to principal axis will be on the same plane . It will be of the same size. i.e, B.C = BC . You can yourself why the image is distorted.
