The software package includes 13 virtual laboratory works from the general physics course for students of higher and secondary educational institutions:
The virtual laboratory practice is implemented in the form of a set of cross-platform graphical applications supplied for various operating systems: Microsoft Windows, Linux, MacOS, iOS, Android, as well as web applications based on HTML5 technology, which provide the ability to remotely perform laboratory work in a web browser. The graphical component of the software uses the OpenGL 2.0 programming interface and component base.
Note:for best performance of online-versions of applications, we recommend using the Microsoft Edge web browser.
