Diffraction

IB Physics: Diffraction

The rotating rods in the interactive physics simulation below have nothing to do with light but help us to understand how the pattern is formed.The idea of modelling the propagation of a wave by considering many wavelets is also used in quantum mechanics. Huygens in 1650 would have had no idea of such things.Deriving the formula for single slit diffraction is probably one of the most difficult bits of the AHL material....
