Exercise 2 - Measuring the Object and Image Distances for Real and Virtual Images
In this exercise we use the lens from the previous exercise to measure object and image distances. In practice, an object is placed on one side of the lens. A screen is then placed on the other side. The distance from the lens to the screen is adjusted until a sharp image is produced on the screen. If an image can be observed on the screen, the image is real and the image distance, i is positive. Otherwise, the image is virtual and is located on the same side as the object. In this case i is negative. For a converging lens, a real image is always produced when the object distance is greater than the focal length. When the object distance is less than the focal length, the image is virtual and no image will be formed on the screen. The method used to locate a virtual image is called the parallax method. (You will learn how to do this in the lab. To get acquainted, read the lab manual.)
The link below opens a window which shows the lens, object and image locations, and the rays to produce the image. Your task is to read the distances and then enter the values in the table below. Enter the numbers with one decimal point. Also determine if the image is real or virtual and whether it is upright or inverted. For an example click here. (Learn more about ray tracing from java applet simulations.)
For the object/image diagram, I need to find the object distance (cm), image distance (cm), if its uprighted or inverted, and finally if its real or virtual image
From what I can tell from the photo, the object is at 2cm, focal at 21, I dont know what the other arrows symbolize.
The last picture is an example that they give, thanks!

The distance between center of the lens and position of the object is 14 cm.
The distnace of the focal points on both side of the lens is 6 cm from the center of lens.
The distance of the image from the center of the lens is 10.6 cm.
the image is formed below the x-axis. therefore, the image is inverted.
the object is beyond the twice of the focal lenght. so, the image formed is real and small in size, and forms between f and 2f on other side of the object.
