C3 activity: Two slit interference
From single slit diffraction to two slit interference. In the process of working through this activity you will observe a fringe pattern that changes with slit width and separation, understand that the fringes are formed as a result of path difference and derive the "Young's slits" equation. On top of this, diffraction continues to play its part; you will explore the effect of diffraction in fringe formation. Topics:...
