E112

The document summarizes an experiment to determine the focal length of converging lenses using the thin lens equation and calculate magnification. The experiment involved setting up lenses and objects at various distances and measuring the image distances. The results showed clearer images form when the object is closer to the lens, and magnification decreases as the object moves further from the lens. In conclusion, the experiment successfully used the thin lens equation to calculate the focal length of converging lenses and measure magnification under different object distances.

Experiment No.

112: Thin Lenses


Esteves, Ralph Gerald D.

Introduction
Experiment No. 112 is about thin lenses. A lens is a transparent material that has two non-
parallel curved edges or one plane and one curved edge. A lens that is thick in the middle
part of it is called converging lens. If the lens is thinner, it is called diverging lens. And the
focal length is the one dictating the magnifying ability of the lens. In this experiment the
group was asked to determine the focal length of a converging lenses using the equation of
the thin lens equation and to compute the magnification using height of the image and object
and its distance.

Results and Discussion


First the group did the set-up for the experiment and computed for the value that they would
want to achieve. And after that they did the exact experiment and wanted to see the most
solid image and got its value. What the group got is that if the image is too far from the lens
the image produce is not clear or solid. An the further the object from the lens the
magnification of the object becomes smaller.

Conclusion
Overall the group performed the experiment well they obtained or calculated for the image
magnification. And got the focal length of the converging lens with the use of thin lens
equation.
