Physics laboratory with smartphone: sound and light

Abstract

We applied smartphone technology to deliver key concepts in light and sound in the Physics Laboratory course. We used the Physics Toolbox Sensor Suite app to demonstrate the spatial and material dependence of the sound intensity level and illuminance. Self-contained modules, which consist of instruction, handouts, and analysis, are provided on the University’s Learning Management System platform to allow students to perform self-directed study on the concept through self-exploration and collaborative experimental activity. This work provides an example of an alternative but potentially powerful learning ecosystem for the future.
