Convering Len

    In a conversing lens, if the object is not within the focal point, then the magnification is "-". But in the case where the object is placed in the focal point, then the magnification is "+"?

    Yes (you mean a converging lens). A "negative" linear magnification just means that the image is erect (and virtual). Read this: http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/raydiag.html#c2"
