| Summary: | At the present article we refer to the pedagogical use and the construction of an experimental device whose cost is minimum to measure periods, specifically of a simple pendulum. In this case the low-cost instruments are available to the teachers at schools. Its operation is similar to the Photogate, an electronics device that contains emission and reception of infrared light. The new suggested device changes light into sound during its operation so we denominated it, Soundgate. |
