• Abstract:

   This work consists of the experimental investigation of wave phenomena using devices developed with technologies that allow greater depth in the concepts studied in physics classes. The activities carried out range from setting up experiments, collecting and analyzing data to preparing teaching materials, as well as preparing practical guides. The phenomena studied are investigated through three experiments: the determination of physical quantities of simple harmonic motion in a mass-spring system, the measurement of the speed of sound using a multichronometer with data processing, and the analysis of the refraction of a two-dimensional wave on a liquid surface.
  As a teaching tool, these experiments were applied to 2nd year high school students at IFTM Campus Patrocínio, with the aim of developing their practical skills in the laboratory. For execution, a set of diverse experiments and high quality and precision equipment were used. These devices were developed by the company CIDEPE – Industrial Center for Teaching and Research Equipment. Along with the equipment, CIDEPE provides experimental activity books containing the user manual for each of them, used during each experiment. The analysis and study of the data obtained in each experiment allows us to explore and relate the physical concepts studied in the wave area, as well as analyzing the impact of instrumentation on physics teaching.
