3. The two loudspeakers in the drawing are
producing identical sound waves. The waves
spread out and
overlap at the point
P. This situation is
Contral
analogous to
Young's double-slit
experiment, except
that sound waves are being used. What is the
difference l2 -/ in the two path lengths if point P
is at the second sound intensity maximum from
the central sound intensity maximum? Express
this difference in terms of the wavelength 2 of
the sound.
