Woo, Yura; Ju, Young-Gu – Physics Education, 2019
In this paper, we present the details of the development of a smartphone spectrometer for education using a 3D printer and characterized the performance by comparison with a paper craft spectrometer. The optical design and the narrow slit used in the build resulted in the formation of accurate images of the slit on the image sensor leading to a…

Nunn, John – Physics Education, 2016
A cordless mouse with an added reed switch is used as a wireless data logger to record every time the wheel of a trolley completes a revolution. The limitations of the system in terms of maximum clicking rate and spatial resolution are considered and data obtained from the descent of a trolley down a ramp at various different angles is analysed in…

St. John, Stuart A. – Physics Education, 2012
The purpose of this work was to investigate ways in which everyday computers can be used in schools to fulfil several of the roles of more expensive, specialized laboratory equipment for teaching and learning purposes. The brief adopted was to keep things as straightforward as possible so that any school science department with a few basic tools…

Ivanov, Dragia Trifonov; Nikolaev, Stefan – Physics Education, 2010
Various wave optics experiments can be carried out using an ordinary compact disc. The CD is suitable for use as a diffraction grating. For instance, a standard CD (700 MB) has 625 lines/mm. In this article, the authors describe two white-light diffraction demonstrations for a large audience, realizable using a CD (as reflection or transmission…

Gintautas, Vadas; Hubler, Alfred – Physics Education, 2009
Lessons and homework problems involving a pendulum are often a big part of introductory physics classes and laboratory courses from high school to undergraduate levels. Although laboratory equipment for pendulum experiments is commercially available, it is often expensive and may not be affordable for teachers on fixed budgets, particularly in…

Libii, Josue Njock – Physics Education, 2004
High-speed photography can show that the shape often used for a newly forming drop is wrong. Knowledge of drop behaviour is important for inkjet printers, and a close look at the formation of drops as given here can enhance critical observation, thinking and analysis.
