Two sound sources driven in phase by the same amplifier
Chapter , Problem 39(choose chapter or problem)
Two sound sources driven in phase by the same amplifier are 2.00 m apart on the axis, one at and the other at At points large distances from the axis, constructive interference is heard at angles with the axis of and and at no angles in between (see Figure 16-31). (a) What is the wavelength of the sound waves from the sources? (b) What is the frequency of the sources? (c) At what other angles is constructive interference heard? (d) What is the smallest angle for which the sound waves cancel?
