Anno LIV – n.3 – luglio/settembre 2021 A Caccia di Spettri I. Costruiamo uno Spettroscopio con uno Smartphone
Home-made spectrometers, based on the use of inexpensive diffraction gratings and a smartphone camera, can be assembled and employed to perform quantitative measurements of spectra from different sources with surprising accuracy. In this paper, we describe some different home-made spectrometers and discuss the calibration procedures and other technical details to perform the measurements. […]
Anno LIV – n.3 – luglio/settembre 2021 A Caccia di Spettri II. Atomi, Stelle e Colori
Home-made spectrometers, presented in the previous work, can be used to perform experiments that address some relevant and engaging topics in Physics. In this paper we will first show some accurate measurements of the spectral lines of discrete spectra, enabling us to accurately determine the Rydberg constant and the wavelength separation of sodium.

Anno XLIII - n.1 - gennaio/marzo 2010 A che altezza si formano le nuvole?
A thermodynamical model of how the formation, uplift and height of clouds depends on ground temperature and relative humidity is described. […]
Anno XXVI - n.1 - gennaio/marzo 1993 Acquisizione di dati dalla porta parallela del PC e misure di tempi
This article explains how to acquire digital data from the parallel port of an IBM-compatible PC. Several experiments in the field of Mechanics, involving time measurements, may be done this way by simply connecting suitable switches (mechanical or optical) to the control lines of the port. […]
