More quantitatively, since the diverging lens is 28 cm to the right of the converging lens, the object distance is do = 28 cm + 12 cm = 40 cm; this is the distance between the diverging lens and the image formed by the converging lens.
Here, is the focal length of the lens in centimeters. The constant 25 cm is an estimate of the near point distance of the eyeâthe closest distance at which the healthy naked eye can focus. In this case the angular magnification is independent from the distance kept between the eye and the magnifying glass.
