Figure P16.40 shows the circular wave fronts emitted by two sources. Make a table with rows labeled P, Q, and R and columns labeled \(r_{1}, r_{2}, \Delta r\), and \(\mathrm{C} / \mathrm{D}\). Fill in the table for points \(\mathrm{P}, \mathrm{Q}\), and \(R\), giving the distances as multiples of \(\lambda\) and indicating, with a \(\mathrm{C}\) or a \(\mathrm{D}\), whether the interference at that point is constructive or destructive.
