A Simple LED Light Source for Multiple Online Experiments

 

A presentation from the 2014 Winter Meeting: Orlando, Florida

Abstract

If experiments conducted outside of the physics laboratory are to become a standard part of online physics courses, the cost to the student must be minimized. Additionally any apparatus used by students without supervision must be easy to use. I will present a relatively inexpensive, easy to use, LED circuit that can be used for experiments in physical and geometric optics as well as a measurement of Planck's constant. Using one piece of apparatus for multiple experiments can help control costs. Using the same apparatus multiple times can help the student gain confidence and reduce the overall learning curve for the laboratory portion of an online course. Data from experiments will be shown.
