Question 2
are two coherent sources of sound having no initial phase difference. The velocity of sound is 330 m/s. No maxima will be formed on the line passing through and perpendicular to the line joining . If the frequency of both the sources is :Question 3
Two sound speakers are driven in phase by an audio amplifier at frequency . The speed of sound is . The speakers are on the -axis, one at and the other at . A listener begins at and walks along a line parallel to the -axis at a very large distance away. At angle she will first hear a maximum (after ) sound intensity.
