0Linear magnification of a mirror is the ratio of height of the image to the total height of the object, thus, Linear magnification = Height of Image Height of Object If “h1” be the height of the object placed in from t of a mirror and if “h2” be the image formed , the n linear magnification “M” produced by the mirror can be represented as under:- M = h2 h2 However linear magnification of a mirror is also equal to the ratio between image distance and object distance form a mirror but with negative sign as represented as under:-
M = - v/u
Where v = Image distance And u = object distance of a mirror. If the magnification has a positive (plus) sign, the n the image formed will be virtual and erect and if it has a negative (minus) sign, the image formed will be real and inverted.
