Creating an elliptical sheet |
Emergent behaviour (diffraction) - diffraction.taoThis script creates two rectangular sheets and joins them together using the Join statement. The boundary between the two sheets is then locked in several places leaving a few `slots' where the waves can get through. A short impulse is applied to one of the sheets named verb|source| and the resulting wave fronts interfere after having passed through the slots to form diffraction patterns.
