Sharifov, Galib Movsum oghlu – Physics Education, 2020
This article deals with an exploration of a double superior mirage obtained in laboratory conditions and its contribution to the deep understanding of light events in specialized schools. It was revealed that an explanation of the formation process of a double superior mirage plays a key role in the adoption of knowledge on reflection and…

Coramik, Mustafa; Özdemir, Erdogan – Physics Education, 2021
In this study, it is aimed to develop practical teaching activities that can be used in optics teaching. For this purpose, a virtual laboratory environment was created in RayLab which is an application for design and simulation of optics on the iPad/iPhone. In this context, the dispersion of white light in the prism, the relationship between the…

Hachmi, Ali; El Hadi, Mohammed; Essaadaoui, Rachid; Mommadi, Omar; Ouariach, Abdelaziz; El Moussaouy, Abdelaziz – Physics Education, 2022
The Arduino board and its communication with several sensors are becoming more and more popular in the physical science community. They offer inspiring possibilities for learning different physical concepts. In this article, we focused on creating a very practical educational system for experimenting with diffraction of laser light and graphically…

Amirjani, Amirmostafa; Koochak, Niloofar Namazi; Haghshenas, Davoud Fatmehsari – Journal of Chemical Education, 2019
In the laboratory experiment described here, students synthesize silver nanostructures (AgNS) with different shapes and sizes to elucidate the shape- and size-dependent optical properties of nanostructured materials. Students also develop understanding of some thermodynamic and kinetic aspects of the synthesis process through this experiment. In…

Rosi, Tommaso; Gratton, Luigi M.; Onorato, Pasquale; Oss, Stefano – Physics Education, 2019
We propose to reconsider the well-known experiment about the interference of white light from a thin soap film by adopting as an illuminating source the RGB triad produced by a LED projector. The interference pattern shows up in a particularly fascinating way and it contains direct, essential information about both the wave nature of light and of…

Singh, I.; Khun Khun, K.; Kaur, B. – Physics Education, 2018
Excel spreadsheets are used as an excellent tool in physics laboratory experiments related to wave optics. This paper presents a simple way to simulate diffraction of waves through a slit using Excel spreadsheets without any tedious programming. These simulations are used to visualize the effect of variation of different parameters such as number…

Kellett, Sarah – Teaching Science, 2015
As part of the celebration of the international year of light and light-based technologies, this article presents an activity involving boiling water, sharp knives, gelatin powder, and a laser pointer. Students are instructed never look directly at a laser pointer because it can damage the eyes, and to make sure a responsible adult is present at…

Putri, Liandha Arieska; Permanasari, Anna; Winarno, Nanang; Ahmad, Nur Jahan – Journal of Science Learning, 2021
Laboratory activity is closely related and yet is essential in the process of science teaching-learning. The hands-on laboratory experiment is the one normally used in school. Particularly with the state of online schooling, it is quite challenging to perform a hands-on laboratory activity. The combination of inquiry-based learning with virtual…

Joseph, Ariana; Budden, Katherine; Cisek, Richard; Tokarz, Danielle – Journal of Chemical Education, 2018
In a university third-year instrumental chemistry laboratory students build a laser based polarimeter for determining light scattering with commercially available optical components used in modern optics research laboratories. During this laboratory experiment, students learn that solutions containing molecules which scatter light also influence…

Ladino, Luis A.; Rondón, Hermilda S. – Physics Education, 2018
The purpose of this paper is to present and discuss an alternative solution to an experimental problem given to high school students in the XXII Ibero-American Physics Olympiad held by Colombia this year. From the measurements of electric current and potential difference across a small tungsten filament lamp students should find the dimensions of…

Semay, Claude; Lo Bue, Francesco; Mélin, Soizic; Michel, Francis – Physics Education, 2018
In 1849, Hippolyte Fizeau determined the speed of light in a famous experiment. The idea was to measure the time taken for a pulse of light to travel between an intense light source and a mirror about 8 km away. A rotating cogwheel with 720 notches, that could be rotated at a variable speed, was used to chop the light beam and determine the flight…

Kutschera, Ellynne; Dunlap, Justin C.; Byrd, Misti; Norlin, Casey; Widenhorn, Ralf – Physics Teacher, 2013
We designed a physics laboratory exercise around pulse oximetry, a noninvasive medical technique used to assess a patient's blood oxygen saturation. An alternative to a traditional optics and light lab, this exercise teaches the principles of light absorption, spectroscopy, and the properties of light, while simultaneously studying a common…

Jenkins, Samir V.; Gohman, Taylor D.; Miller, Emily K.; Chen, Jingyi – Journal of Chemical Education, 2015
The rapid academic and industrial development of nanotechnology has led to its implementation in laboratory teaching for undergraduate-level chemistry and engineering students. This laboratory experiment introduces the galvanic replacement reaction for synthesis of hollow metal nanoparticles and investigates the optical properties of these…

Kozyulin, M. V.; Silagadze, Z. K. – European Journal of Physics, 2011
Gravitational light deflection, predicted by general relativity, is a fascinating phenomenon with numerous important applications in astronomy, astrophysics and cosmology. At first sight, there is no analogous effect in electrodynamics because Maxwell's equations are linear and, therefore, a photon does not interact with the electromagnetic field…

Branca, Mario – Physics Teacher, 2010
A mirage can occur when a continuous variation in the refractive index of the air causes light rays to follow a curved path. As a result, the image we see is displaced from the location of the object. If the image appears higher in the air than the object, it is called a "superior" mirage, while if it appears lower it is called an "inferior"…
