In this study, it is aimed to develop practical teaching activities that can be used in optics teaching. For this purpose, a virtual laboratory environment was created in RayLab which is an application for design and simulation of optics on the iPad/iPhone. In this context, the dispersion of white light in the prism, the relationship between the refractive index and the wavelength of the light and the recombination of the dispersed white light were examined. It was seen that the virtual experiment results obtained in the activities are compatible with the theoretical results and the real experimental situations.
