Two waves shown below with the same amplitude, A, and wavelength, λ, and traveling in the same direction. Initially the sources (dot at the origin) are also at the same point. The source of the second wave is then displaced by a distance dx. a) For what values of dx will the superposition of the two waves show total constructive interference? Give at least two values in terms of λ. b) For what values of 8x will the superposition of the two waves show total destructive interference? Give at least two values in terms of λ.

Question
I needed help with this question. I understand that if the waves were to start at the same point, then the shift would be 0, 2pi, 4pi, and so on, however I do not know if this would change because the wave has shifted.
