Two isotropic acoustic sources are located a distance of 10.0 mapart along an x-axis. The source
at x = 0 puts out a total acoustic power of 1.00 mW, while thesource at x = 10 m puts out a total
power of 2.00 mW. Assuming that the acoustic intensity at any xbetween the sources is just the
sum of the intensities arriving from the two sources,
(a) at what value of x (to three significant figures) between thesources is the acoustic intensity a
minimum? (Ignore any effects due to absorption in the air.)
(b) What is that minimum intensity, and what is the correspondingabsolute intensity level in dB?
