Prelab Questions Give the algebraic relationship between the focal length, the distance from the object to the lens or mirror, and the distance from the lens or mirror to the image. Thick Converging Lens As in part 1 of this lab, we're going to measure the focal length of a converging lens - a lens that is thicker...

Now, a diverging lens with focal length having a magnitude of 20 cm is placed 10 cm to the right of the converging lens in problem that has a 2 cm tall object placed 12 cm to the left of a converging lens with focal length of magnitude 15 cm. Determine the location of the final image formed by both lenses (in relation to the diverging lens) and the magnification of the final image. State whether the final image is...

Two converging lenses are placed 20 cm apart. An object is placed on the left of the first lens, at a distance of 30 cm. The first lens has a focal point of 10 cm and the second lens has a focal length of 20 cm. a) Using a ray diagram determine the type of image formed by the first lens. b) Calculate the position of the image formed by the first lens. c) Find the magnification of the image...

1 1 Problem 2: Two lens system (3 points) When two thin lenses are in contact, the combination may still be considered as a thin lens. The focal distance of the combination, fc, is given by 1 ==+ eq. (1) fc fi 12 where f and 12 are the focal distances of the two lenses in contact. Assume two converging lenses (10 cm and 20 cm focal distances) are in contact and do -15 cm. a)...
