An object stands on the common central axis of two thin, symmetric lenses. The object is placed 15.0 cm in front of the first lens (converging lens) whose focal length is 10.0 cm. The second lens is a diverging lens whose focal length is also 12.0 cm. The distance between the lenses is 40.0 cm. a.) Determine the characteristics of the final image by using thin-lens and magnification equations. Give your reasoning. b.) Find the location of the final image by using ray diagrams (sketch the rays clearly). Object f₁ 15 cm 1st Lens f₁ 40 cm 420 2nd Lens
