A thin convex lens of power 2D & a thin concave lens of power-2D will act as what?
Asked by Devesh | 5th Feb, 2012, 09:23: PM
you mean to say the combination of these two lenses?
the net power=0 D
so 1/f =0
so the rays parallel to the principal axis will appear to meet at infinity.so there woud not be any deviation.
