An object placed 20 cm in front of a lens results in an image being formed 24 cm behind the lens. Each surface of the lens is convex (bulging away from the optical plane) with the same radius of curvature, and the index of refraction of the glass composing the lens is Tiens =1.4. What is the radius of curvature of either side of this lens (to the nearest tenth of a cm)? Note, once again, the focal length of...

8. An object is placed 1 m in front of a convex lens with an 80 cm focal length. A convex mirror is then placed 1 m behind the lens. The radius of curvature of the mirror is 50 cm. 1. Where is the final image of the object (the image formed by light that has passed through the lens twice), with respect to the lens? 2. What is the total magnification of the final image? 3. Is the image...

1) An object with height of 2.5 cm lies 10 cm in front of a lens with focal length of 6 cm. c) Suppose that this image serves as the object for a second lens that has a focal length of + 4 cm. The second lens is placed 6 cm beyond the image serving as its object. Where is the image formed by this second lens? d) What is the magnification produced by the second lens?
