Question

the linear magnification produced by spherical mirror -1 . Analyizing this value state the type of mirror and position of object with respect to the pole of the mirror.

Answer 1

Magnification is the difference in enlargement or smaller the image

Answer 2

if the magnification is greater then the object height then its a concave mirror n the position of the object lay bwt c and f , at f and bwt p and f ......
if the magnification is lesser then the object height it can b concave mirror or even convex mirror ... if its concave the the position ll b at infinity, beyond c . ....... if its convex then the position of object will b at infinity , bwt infinity n pole.
.... .. its just the size of object n magnification
