Consider an object with s=12cm that produces an image with s1=15cm. Note that whenever you are working with a physical object, the object distance will be positive (in multiple optics setups, you will encounter "objects" that are actually images, but that is not a possibility in this problem). A positive image distance means that the image is formed on the side of the lens from which the light emerges. (1)Find the focal length of the lens that produces the image...

A diverging lens of focal length −17cm and a converging lens of focal length 15cm are separated by 42cm. An object is placed 30cm to the left of the diverging lens. Compute the distance (with correct sign) the final image forms from the converging lens.
A converging lens of 15cm focal length is placed on an optical bench that is 120cm long. An object fixed at 0.0cm and screen is placed at 140.0 cm. Measuring from the object end of the bench, determine the two positions of the lens for which an image will be focused on the screen. Find all magnification in each case.
A 2.0 cm tall object is 15cm in front of a converging lens whose focal length is 20 cm. a. what is the image distance? b. what is the magnification? c. what is the height of the image?
An object is placed 12cm away from a convex lens that has a focal length of 5cm. a. Sketch a ray diagram for the situation. b. Is the image real or virtual, magnified or reduced, and upright or inverted? c. Determine where you should put a screen in order to project the image clearly. Is your answer consistent with the ray diagram? How do you know?
Consider a converging lens with focal length locm. Find graphically the image location for an object at the following distances from the lens: A: 10 cm B: 20 cm
c. An object is placed 12cm away from a diverging lens with a focal length of -6am. i. (l pt) Use this information to caloulate the image distance and the magnification. i. (2 pts) Draw an accurate ray diagram for the above set-up using the rules for "easy" rays.
(a) The relation between the object distance S, the image distance S' and the focal length f of a lens producing a real image is given as 1 1 1 S S This is called the Gaussian form of the thin lens formula. Another form of the formula, the Newtonian form, is obtained by considering the distance x, from the object to the first focal point and the distance x; from the second focal point to the image. Show that...
Find the focal length of a lens that produces an inverted image five times the size of a small object placed on the optical axis, 26.4 cm from the lens.
