C3 PBL: Multiple slits support
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 slits The 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. To plot the max...
