Abstract
The Young’s interference experiment was one of the well -known experiments that shows the wave nature of light. It is the fundamental of several quantum optics experiments nowadays. We reproduce this famous experiment in VirtualLab Fusion, by using a double slit with adjustable slit width and slit distance. With a single point source, we examine the influence from the slit width and the slit distance on the interference; then with an extended source we observe how the interference contrast changes with the lateral extension of the source.
