Question

THE LINEAR MAGNIFICATION produced br a spherical mirror is -1. What is the type of miror, nature and position of object

Answer 1

$\textbf{What is Magnification? }$

It is the ratio of height of image of object to the height of object.

So, if magnification, it means that image of the object is inverted and real.

$\textbf{Now, when magnification is 1? }$

Magnification will become 1 only if height of object = height of image.

Position of object will be at the centre of curvature, upright at 90°.
