Make a table with fows labeled \( P, Q \), and \( R \) and columns labeled \( r_{1} \). \( r_{2}, \Delta r_{r} \) and \( C / D \). Fit in the table tor points \( P \), \( Q \), and R. giving the distances as muliples of \( \lambda \) and indicating, with a \( C \) or a \( D \), whether the inlerlerence at that point is The figure shows the circular wave fronts emitted by tao constructive or destructive. wave sources.
