Back to Wave OpticsTwo coherent sources of sound, S
1
and S
2
,
produce sound waves of the same wavelength,
\lambda = 1 m, in phase. S
1
and S
2
are placed 1.5 m
apart (see fig). A listener, located at L, directly
in front of S
2
finds that the intensity is at a
minimum
when he is 2 m away from S
2
. The
listener moves away from S
1
, keeping his
distance from S
2
fixed. The adjacent maximum
of intensity is observed when the listener is at
a distance d from S
1
. Then, d is :
