This Two Slit Diffraction model allows the user to check the effect of adding a slab of thickness t and index of refraction n in front of one of the slits in a Fraunhofer two slit diffraction setup. The user can modify the slit width, the slit separation, the wavelength of the incident light, the distance separating the slits from the screen, and also the thickness of the slab and its index of refraction. The scale of the diffraction pattern can also be changed.

dear sir
the interference simulations on introdusing a medium inthe path really superb
why dont you try measurement in newtons rings?
best wishes
