Professor McNair 30 April 2018 Physics 102 Lab 41- Focal Length of Lenses
Purpose: The purpose of this lab was to figure out the properties of a converging and diverging lenses. Also, be able to determine the focal length of a converging lenses both by a real image of a distinct object by finite object and image distance. Lastly, be able to determine the focal length of a diverging lens using it in combination with a converging lens to form a real image. Materials and Apparatus: The materials and apparatus that were used in this lab are as followed: optical bench, holder for the lenses, a screen to form images, meter stick, tape, lamp with objects on face, three different lenses. Procedures: First we placed one of the three lenses on the holder on the optical bench and placed the screen in it holder on the optical bench. Then place the bench in front of a window point to some distance object. Then make any adjustments to make the lens appear sharp. You will only be able to form the sharp picture for two of the lenses. After determining which distance is
