2. An object is placed in front of two thin symmetrical convex lenses with focal lengths of F1 +10 cm and F25 cm, with a lens separation of D-42 cm. The object is 15.0 cm from lens 1. Where is the final image of the object and what is its magnification? (10 points) [Please use reverse side if you need more room.

An object is placed in front of two thin coaxial lenses 1(convex) and 2 (concave). The focal points for lens 1(convex) and 3cm from the lens: those for lens 2 (concave)are 6cm from the lens. The lenses have separation L=8.5 cm, and the pencil is 9 cm to the left of lens 1. a) Where does the system of two lenses produce an image of the object? b) The object has height h=2mm. What is the height of image 2?...
webassign.net Active Figure 26.25 Thin Lenses The animation below shows a thin lens, an object (blue arrow) and an image (tan arrow). Three rays are shown that locate the positic orientation, and size of the image. Readouts are provided for object distance, object height, image distance and image height. Instructions: Click and drag the blue object. Click the button in the lower left of the applet window to toggle between a conc convex lens. Explore Images formed by thin lenses...

Two positive thin lenses are separated by a distance of d. The focal lengths of the lenses are f_1 = 10 cm and f_2 = 20 cm. The desired throw of the system, the object to image distance, is T = 80 cm and the desired magnification is M = -1.1. a) Use what you know about the conjugate matrix for a two lens system to solve to the distance between the lenses. Express your answer in cm. b) Where...
Two converging lenses are separated by a distance of 20 cm. The first lens has a focal length of 5 cm and the second lens has an unknown focal length that you need to calculate. When an object is placed 8 cm in front of the first lens you measure a total magnification of M=-1.8 (That is, the magnification caused by the two lenses). Answer the following questions: 1. location of the image found by the first lens 2. magnification...
An object is located to the left of two lenses that are separated by a distance of 40 cm. The object is located at p1 = 45 cm in front of the first (diverging) lens with a -30 cm focal length, as sketched by an arrow in the figure below. The final image created by the two lenses is located 8.6 cm to the right of the second lens. (a) Clearly draw in the space below at least two of...
Two converging lenses, each having a focal length equal to 11.0 cm, are separated by 36 cm. An object is 22 cm to the left of the first lens. a) Findthe position of the final image using both a ray diagram and the thin-lens equation. cm to the right of the object (b) Is the final image real or virtual? O real O virtual Is the final image upright or inverted? O upright O inverted (c) What is the overall...
9. -15 points KatzPSE1 38.P.076 My Notes Ask Your The figure below shows an object placed a distance doi from one of two converging lenses separated by s 1.00 m. The first lens has focal length fi 23.0 cm, and the second lens has focal length 2 47.0 cm. An image is formed by light passing through both lenses at a distance = 12.0 cm to the left of the second lens. Include the sign of the value in your...
2. Two thin lenses, one a converging lens and the other a diverging lens, are arated by 1.00 m along the same principal axis, as shown in the figure. The magnitude of the focal length of the converging lens is 25 cm, while the magnitude of the focal length of the diverging lens is 40 em. An object 8,25 cm tall is placed 35 cm to the left of the converging lens. (a) Where is the final image produced by...
