The two-dimensional snapshot of the interference of waves from two sources is shown in the figure, where bright lines represent wave crests.

Part 1#

With an arrow identify and label the location of the two sources (call one source 1, and the other source 2) of these waves. On the same diagram at the edge of figure identify with an arrow the location of the \(m = -2\), \(m = 0\) and \(m = 2\) antinodal lines.

Upload your labeled diagram as png named ‘file’.
