I am having difficulty grasping what to do for this problem:(adsbygoogle = window.adsbygoogle || []).push({});

Two point sources located (0, +/- 2.5(lambda)) are generating waves in phase. Compute the distance from the x-axis to the first nodal line at

x=50(lambda)

I'm not sure what equations to use. My physics instructor is terrible and we don't even use a text book......instead we have to read his "readings". I don't really grasp wave motion very well..............if u have a link to a wesite that can help be out that would be great.

Thanks!
