Vedclass · Answer

(A) rear-view mirror in vehicles is a convex mirror.Convex mirrors always form virtual,erect,and diminished images of objects placed in front of them.Since the image is always diminished (smaller than the object),the height of the image $(h')$ is always less than the height of the object $(h)$.Magnification $(m)$ is defined as the ratio of the height of the image to the height of the object,i.e.,$m = h'/h$.Because $h' < h$,the magnification $m$ is always less than $1$.
