AP Physics Experiment – Geometric Optics (Lenses) Purpose To determine the focal length and nature of the images formed by a converging lens. To determine the focal length of a diverging lens. Procedures Part 1 – Converging Lens 1. Place the converging lens in the holder at the 50cm mark on the meter stick (optical bench) and the screen at approximately the 70cm mark. 2. Move the screen along the meter stick towards and away from the lens until the image of a distant object at least 100m away appears as small as possible on the screen. [Note that the image can be best obtained by placing your back to a window in a darkened lab and aiming the meter stick back over your shoulder while adjusting the screen to focus on a distant object.] 3. Measure and record the distance in centimeters between the lens and the screen as the focal length (F c ) of the lens. 4. Place the light source (lit candle or ray box) at or near the end of the meter stick. 5. Place the lens a distance greater than twice its measured focal length from the source.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
