- 2. Show that the minimum distance between a real object and its real image given by a convergent lens of focal length f is 4f. Get q as a function of p from 1/p + 1/q = 1/f. Take the derivative of s = p +q to find the value of p for which s is minimum.1) A piece of thin spherical shell that has a radius of curvature of 145 cm is silvered on both sides. The concave side of the piece forms a real image 500 cm from the mirror. The piece is then turned around so that its convex side faces the object. The piece is moved so that the image is now 30 cm from the piece on the concave side.6. A thin converging lens of focal length f =+12.0 cm is separated from a thin diverging lens by a distance d = 24.0 cm . The focal length of the second lens is f, =-48.0 cm. An object with height y = 4.20 cm is placed on the optical axis at p, =18.0 cm in front of the first lens. Pay attention to +/- signs. What is the location of the image produced by the first lens alone, i ? а. b. What is the lateral magnification m , produced by the first lens alone? с. Where is the final image of the two lens system located relative to the second lens (i.e. what is i,)? d. What is the total magnification of the two lens system, M ? What is the height of the final image, y, ? е. R/V? - Is the final image real or virtual? g. I/NI? - Is the final image inverted or not inverted (relative to the object in front of the first lens)? f.
