Practical: Two slit interference

IB Physics: Practical: Two slit interference

In this exercise the interference and diffraction of light passing through narrow slits will be observed and understood by comparing to a GeoGebra simulation.The original experiment was performed with sunlight but it is simpler to use a laser as this is parallel light of only one wavelength so easier to deal with. For this experiment you will need a ready prepared double slit, you could make your own by scratching lines...
