Interference pattern is coherence between two interfering waves i.e they should come from same source.
When two waves are said to be coherent when they maintain zero phase difference forever.As phase difference between two interfering waves is zero ,they may interfere constructively (or) destructively producing bright or dark fringes.
If we consider two flash lights with zero phase difference is not maintained and interference pattern is irregular i.e maximum and minimum are not consecutive.they are in a different way.

(25 marks) In class we discussed the interference pattern produced by eight equally spaced, narrow slits (see powerpoint Ch. 4 pg 31). We used phasor diagrams to show that each of the cases o = 1/4, 1/2, and a gives intensity minimum. We claimed that minima also occur for 0 = 31/4, 51/4, 31/2, and 71/4. Draw the phasor diagram for each of these four cases, and explain why each diagram proves that there is in fact a minimum.

1. It is hard to get the bars to be parallel in this experiment. Explain why the bars tend to be so wiggly That happens because there is not match friction between the glass plates and it makes it hard to move them gradually relatively to each other, plus the surfaces of the glass plates are not entirely even which makes the friction vary in different areas of the glass plates and their movement...
