“…3). 13,14 While it is possible to use the grating both in reflection and transmission, we asked the students to work in transmission alone for safety reasons (in order to avoid laser question we are confronted with is therefore how to "reduce" the acceleration so that it becomes feasible to measure.…”

The pandemic triggered by the SARS-CoV-2 virus has produced worldwide interruptions of face-to-face teaching activity in both schools and universities. In Italy, the quarantine began in the second half of February 2020 and lasted for all the second semester of lectures. The University of Bologna, where all the authors of the present article are based, developed and activated several interfaces necessary to efficiently deliver online teaching courses with the utmost speed. The framework used by the authors is based on a common platform, Microsoft TEAMS, available to all teachers at Bologna University.

“…Using compact disks as diffraction gratings to perform diffraction experiments by multiple slits is very well-known and has been previously described by many authors (see, for example, [5][6][7][8][9][10][11][12][13]). It was also recently tested as a home-lab experiment during the lockdown due to COVID-19 pandemic [14].…”

Low-cost experiments have the advantage of being affordable to schools, universities, and families. In the particular case of optics, these experiments can be important to help students understand the properties of light and optical phenomena. In this article, we demonstrate optical experiments to be carried out at home by students learning remotely. These experiments were designed and performed at the 16th Summer School in Physics, which is a five-day activity for high school students organized by the University of Porto. This activity was organized remotely, with all lectures and activities being performed through video conferencing. The materials needed for the proposed experiments were sent by post to students before the beginning of school. The students were able to build optical experiments from scratch, perform measurements, analyse data and present their findings on the last day of the school in a public session dedicated to online presentations.

“…However, the mechanism of the detector allows a much faster automatic calibration using an optical grating. A simple compact disc (CD) can be used as an optical grating [21] to keep costs low, see figure 6. We remove all non-transparent layers, including the reflecting layer from the CD using cellotape.…”

Inexpensive Mie scattering experiment for the classroom manufactured by 3D printing

Scattering experiments are fundamental for structure analysis of matter on molecular, atomic and sub-atomic length scales. In contrast, it is not standard to demonstrate optical scattering experiments on the undergraduate level beyond simple diffraction gratings. We present an inexpensive Mie scattering setup manufactured with 3D printing and open hardware. The experiment can be used to determine the particle size in dilute monodisperse colloidal suspensions with surprisingly high accuracy and is, thus, suitable to demonstrate relations between scattering measurements and microscopic properties of particles within undergraduate lab course projects.
