Superposition
How would you expect the interference patterns in figure 3 to change in figure 3 to change if; a) the tow dippers are moved further apart? b)the frequency of the waves produced by the dippers is reduced? For part b; my friend told me that in part b there would not be interference patterns but that didn't make sense hence they do interfere as the sources are still coherent?
