This work presents the development and programming of a Graphical User Interface (GUI) using the CERN’s ROOT framework. This virtual laboratory draws an analogy between the phenomenon of Frustrated Total Internal Reflection (FTIR) and the one-dimensional Tunneling Effect, a commonly cited intersection in the literature between quantum mechanics and classical optics. This scientific-technological resource employs an approach to the tunneling effect by varying parameters of the physical system and analyzing its transmission coefficient. The developed GUI is a valuable tool for teaching quantum mechanics, particularly in the area of the Tunneling Effect. Its application in the classroom can enhance students’ understanding and facilitate the learning of abstract concepts.
