Question

The two sources S₁ and S₂ shown in Fig. emit waves ofthe same wavelength λ and are in phase with each other. Suppose S₁ isa weaker source, so that the waves emitted by S₁ have half the amplitude 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.

Antinodal curves (red) mark positions where
the waves from S, and S, interfere
constructively.
At a and b, the waves
arrive in phase and
interfere constructively.
m = 3
m = 24
m = 1
m = 0
m = -1
m = -2
m = -3
At c, the waves arrive
one half cycle out of phase
and interfere destructively.
m = the number of wavelengths A by which
the path lengths from Sj and S2 differ.
