Bestari, L. F.; Sarwanto; Pujayanto; Syam, W. P.; Harjunowibowo, D. – Physics Education, 2022
Light spectrum dispersion is an exciting subject in science because of its beautiful atmospheric colour phenomenon which attracts students. However, to see the phenomenon is not easy since it needs a spectrometer, which is commonly expensive. Therefore, the present study aims to describe a low-cost spectrometer for investigating lighting spectrum…

Hughes, Stephen; Gurung, Som – Physics Education, 2021
Huygens' principle in which every point on a propagating wave acts like a point source of radiation is a foundation principle of physics. Normally, Huygens' principle is demonstrated by passing a wave, for example a water or light wave through an aperture comparable in size to the wavelength. In this paper, an experiment is described in which a…

Chiang, Chun-Ming; Cheng, Han-Yang – Physics Teacher, 2019
This study aims to measure Brewster's angle of glass and acrylic brick with an easy-to-obtain mobile application (app) by changing the tungsten light source to a red laser. The popularization of the smartphone has inspired many to use its various built-in sensors to carry out general physics experiments. Many others have adopted both a laser and a…

Ishafit; Mundilarto; Surjono, H. D. – Physics Education, 2021
This paper describes the development of a light polarization experimental apparatus for a remote laboratory. The apparatus had been developed by controlling the analyzer rotation using a stepper motor controlled via the Arduino. Device control and data acquisition applications were developed with LabVIEW which provides remote control panel…

Hahn, Marcelo; Cruz, Frederico; Carvalho, P. Simeao; Ferreira, Vanessa; Marques, Filipe; Macieira, Cláudio – Physics Education, 2021
Renewable energy is a trending topic due to its importance in today's society especially because of global warming. Because of its importance, this topic should be discussed at schools in an inclusive education environment. Experimental work is a very good activity to provide students effective conceptual discussions, but it is necessary to…

Boot, Roeland – Physics Teacher, 2017
There is a relatively simple way of using radioactive material in classroom experiments: uranium glass, which provides teachers with a suitable substance. By using the right computer software and a radiation sensor, it can be demonstrated that uranium glass emits radiation at a greater rate than the background radiation and with the aid of UV…

Bigger, Stephen W. – Journal of Chemical Education, 2016
FlashPhotol is an educational software package that introduces students to the kinetics of transient species and fast reactions. This is achieved by means of a computer-simulated flash photolysis apparatus that comprises all major functional elements and that students can use to perform various experiments. The experimental interface presents a…

Lombardi, S.; Monroy, G.; Testa, I.; Sassi, E. – Physics Education, 2010
A new procedure for performing quantitative measurements in teaching optics is presented. Application of the procedure to accurately measure the rate of change of the variable refractive index of a water-denatured alcohol mixture is described. The procedure can also be usefully exploited for measuring the constant refractive index of distilled…

Kraftmakher, Yaakov – European Journal of Physics, 2008
The "quantum efficiency" (QE) is an important property of a light detector. This quantity can be determined in the undergraduate physics laboratory. The experimentally determined QE of a silicon photodiode appeared to be in reasonable agreement with expected values. The experiment confirms the quantum properties of light and seems to be a useful…

Wakabayashi, Fumitaka – Journal of Chemical Education, 2008
A new type of DVD spectroscope, the periscope type, is described and the numerical analysis of the observed emission and absorption spectra is demonstrated. A small and thin mirror is put inside and an eighth part of a DVD is used as a grating. Using this improved DVD spectroscope, one can observe and photograph visible spectra more easily and…

Bardar, Erin M.; Brecher, Kenneth – Astronomy Education Review, 2008
In this article, we present an overview of a suite of light and spectroscopy education materials developed as part of Project LITE (Light Inquiry Through Experiments). We also present an analysis of how introductory college astronomy students using these Project LITE materials performed on the Light and Spectroscopy Concept Inventory (LSCI)…

Mihas, Pavlos; Andreadis, Panagiotis – Science & Education, 2005
In this paper are presented the views of Al Haytham and his predecessors on the shadows, the rectilinear propagation of rays and the images produced by pinholes. Al Haytham had given erroneous views on the distribution of light in the shadows. Educational applications of these are presented. These applications concern: (a) Simple experiments (b)…

Dean, P. J.; Murkett, A. J. – Physics Education, 1985
Describes how color graphics are built up on microcomputer displays and how a range of colors can be produced. Discusses the logic of color formation, noting that adding/subtracting color can be conveniently demonstrated. Color generating techniques in physics (resistor color coding and continuous spectrum production) are given with program…

Weaver, Dave – 1986
Science interfacing packages (also known as microcomputer-based laboratories or probeware) generally consist of a set of programs on disks, a user's manual, and hardware which includes one or more sensory devices. Together with a microcomputer they combine to make a powerful data acquisition and analysis tool. Packages are available for accurately…
