Ceuppens, S.; Deprez, J.; Dehaene, W.; De Cock, M. – Physics Education, 2018
To improve the teaching and learning materials for a curriculum it is important to incorporate the findings from educational research. In light of this, we present creative exercises and experiments to elicit, confront and resolve misconceptions in geometrical optics. Since ray diagrams can be both the cause and the solution for many…

Dounas-Frazer, Dimitri R.; Ríos, Laura; Pollard, Benjamin; Stanley, Jacob T.; Lewandowski, H. J. – Physical Review Physics Education Research, 2018
The ability to develop, use, and refine models of experimental systems is a nationally recognized learning outcome for undergraduate physics lab courses. However, no assessments of students' model-based reasoning exist for upper-division labs. This study is the first step toward development of modeling assessments for optics and electronics labs.…

Lopez-Arias, T.; Calza, G.; Gratton, L. M.; Oss, S. – Physics Education, 2009
A simple experiment is presented to visualize inferior and superior mirages in the laboratory. A quantitative analysis is done using ray tracing with both photographic and computational techniques. The mirage's image, as seen by the eye or the camera lens, can be used to analyse the deflection and inversion of light rays. (Contains 6 footnotes, 1…

Eaton, T. W. – Physics Education, 1977
Using the simple optical system and photodiode described in this article it is possible to give clear, quantitative demonstrations of all the Fraunhofer diffraction phenomena at single and multiple apertures. These measurements can be related to the theoretical predictions given in standard textbooks. Circuit diagram and optical layout are…

Fabrikant, V. A. – Quantum, 1992
Discusses the energy flux-density of two beams of light of equal energy that are intersected at a given angle. Examines an apparent contradiction to the physics law of conservation of energy known as Vavilov's paradox. (MDH)

Jewett, John W., Jr. – Physics Teacher, 1991
Describes science demonstrations with light-emitting diodes that include electrical concepts of resistance, direct and alternating current, sine wave versus square wave, series and parallel circuits, and Faraday's Law; optics concepts of real and virtual images, photoresistance, and optical communication; and modern physics concepts of spectral…
