In this experiment, you will form an image on a “screen” using lenses.
1 Concave Lens
1 Convex Lens
Ruler
*Sheet of Paper (Any Kind)
Objects in lenses:
- Look through the concave lens at a number of objects, such as your ruler. Note whether the object appears larger or smaller.
- Look through the convex lens, keeping the lens less than 10 cm away from any objects. Now move the lens farther away gradually, and note what happens to your view.
Image Formation:
- Find an area in your room or home with a bright window. Try to dim the inside lights in the area so that the window provides most of the light—it helps if you can use a curtain to limit the amount of light coming in.
- Hold the white paper in front of your eyes in an area that is not directly lit by the window. Using your other hand, hold the convex lens in front of the paper so that it is between the window and the paper, with your eyes on the other side.
- Try to form an image of the window on your “screen” by changing the distance between the lens and the paper—this should occur when the lens is between 10 cm and 20 cm from the paper. Can you make a sharp image?
4. What kind of image did you view on the screen in Part 2?

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?...

1.)
Parallel light rays pass through a concave lens as illustrated in
figure 1. Using the diagram, indicate the focal point of this lens.
2.) A convex lens has a focal length of 100 mm. The lens
produces an image from an object placed 50 cm from the lens.
Determine the distance from the lens to the image in the
magnification of the image.

Don't quite get questions 1-6
For lenses in combination, the image for the first lens is the object for the second. The ray tracing diagram below shows how the rays travel through the system from object to first image/second object and then to second image. The first ray trace gives the location and size of the first image. A second ray trace is performed to find where the second object (which is the first image) creates the second image. It...
