I am going my physics extended essay and I am stuck in explaining my hypothesis. So I am doing an experiment where I have 2 sound sources emitting specific frequencies and I am trying to find fringe (first maximum or the point of constructive interference). Now the problem is I have to use theory to explain why the point of the first constructive interference will decrease as the frequency of emitted sound waves increases. Anyone have an idea please?
