![]() For minus lenses, F 2 is the location at which incoming parallel light rays, via imaginary extension, appear to converge recall that these light rays will actually diverge after striking the minus lens. We have been primarily referring to this F 2 as the “focal point” when doing U + D = V problems. It needs to pull out entirely and slowly push the barrel inside, while looking through the telescope, till the desired object becomes clear. To be specific, F 2 for a plus lens is the location at which incoming parallel light rays will converge to form an image. ![]() The secondary focal point ( F 2) is to the RIGHT of a plus lens and to the LEFT of a minus lens.

Remember that the primary focal point ( F 1) is to the LEFT of a plus lens and to the RIGHT of a minus lens.
