Q35.6 The two sources S₁ and 5₂ shown in Fig. 35.3 emit waves of the same wavelength A and are in phase with each other. Suppose S₁ is a weaker source, so that the waves emitted by S₁ have half the ampli- tude of the waves emitted by S₂. How would this affect the positions of the antinodal lines and nodal lines? Would there be total reinforcement at points on the antinodal curves? Would there be total cancellation at points on the nodal curves? Explain your answers.
