Given info : A convex lens forms an image of magnification -2 of the height of image is 6cm.
To find : the height of object is ...
solution : magnification, m = -2 , negative sign indicates that image is real , inverted.
so height of image, = -6cm
we know, magnification is the ratio of the height of image to that of object.
∴ magnification, m = height of image/height of object =
⇒ -2 = -6cm/height of object
⇒ height of object = 3 cm
therefore the height of object is 3cm.
