Transcribed Image Text:Two identical sources of sound separated by 2 m generate waves that are in phase with each other.
The diagram shows a snapshot in time of the waves from the two sources, where the lines denote
successive crests of the waves (solid lines from one and dashed lines from the other).
11
What is the wavelength λ of the waves? Provide a numerical answer.
Draw the line on the diagram where the path difference of the waves from the two sources is
always zero.
Is the interference on this line constructive or destructive?
Is this a nodal or an antinodal line?
Mark points on the diagram where the path lengths from the two sources differ by X/2, X,
3A/2, and 2A. Join the points to draw all the possible nodal and antinodal lines.
If you walk around the two sources in a large circle with 5 m radius from the midpoint of the
two sources, at how many places will you experience complete sound cancellation?

In this case, we are using the point on the first nodal line, n = 1. Path lengths are then represented with the variable P1S1 and P1S2. The paths leading from each of the sources to the point on the first nodal line are drawn as solid lines. Review the following procedure in order to answer the questions that follow.
