IB Physics: Multiple slits teachers notes

Shine laser light through the 3 parallel slits on the PASCO multiple slit set and observe the subsidiary maxima formed between the main interference fringes.Try modelling 4 and 5 slitsThe easiest way is to add sin functions that are out of phase with each other by the same amount (sin(x), sin(x+a), sin(x+2a) etc.). Varying a will change the phase angle representing the different viewing angles.
