Vedclass · Answer

(A) The lateral magnification $m$ is given by $m = \frac{h_i}{h_o} = -2$. Since $m$ is negative,the image is inverted with respect to the object. For a virtual object (where the object distance $u > 0$),if the magnification is negative,the image formed is real (where the image distance $v Using the mirror formula $\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$,for a virtual object and a real image,the mirror must be a convex mirror. Specifically,for a convex mirror,the focal length $f$ is positive. Thus,the correct configuration is a convex mirror forming a real image.

If the lateral magnification is $-2$ for a virtual object in a spherical mirror,then:
