Treffer: VIRTUAL LABORATORY OF THIN LENSES USING ANDROID SMARTPHONE WITH PYTHON PROGRAMMING

A computer program has been created to simulate a ray diagram on a thin lens using the Python programming language. The program is a ray diagram simulation on a convex lens and a concave lens. The program is built using the canvas, create line, button and motion functions in the object-oriented programming language Python. The object being simulated is a convex and concave lens with a focal length of 10 cm and an object's height of 4 cm. The simulation results are in the form of an interface with the user using computer graphic media and interaction via a touch screen. The program can run on Android mobile phones. The results of ray diagrams on computers and Android cellular phones show that they are in accordance with theory, so that the program can be used as a virtual laboratory material.
