1. Two waves shown in the attachment with the same amplitude, A, and wavelength, lamda, 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 sigma x.

a) For what values of sigma x will the superposition of the two waves show total constructive interference?

b) For what values of sigma x will the superposition of the two waves show total destructive interference?
