Hello folks,

I'm having trouble getting started on this question about waves. I missed the associated lecture and don't know which formulae I need to be thinking about. Any help towards an approach to the questions would be appreciated.
 
Physics news on Phys.org
The register of zero at the 44.4° and 64.6° means that there is maximum destructive interference at these points. I don't think that the two sources can be assumed to be of the same wavelength. I imagine the formula dsinθ = (m+1/2)λ is relevant?

The problem states that "the two sources are driven in phase", which means they have both the same frequency and phase. :smile:

Ah okay. That's progress already. A hint towards getting started?

Go youtube a few videos on wave interference then you'll understand conceptually what is going on. After that you can start thinking about the math.
