If S_1 and S_2 are two point sources emitting light in phase , then what is the shape of interference fringes formed on the screen ?

Two sources are called coherent if they produce waves

Two source of sound, S_(1) and S_(2) , emitting waves of equal wavelength 2 cm , are placed with a separation of 3 cm between them. A detector can be moved on a line parallel to S_(1) S_(2) and at a distance 24 cm from it. Initially, the detecor is equidistant from the two sources. Assuming that the waves emitted by the sources are in phase, find the minimum distance through which the detector should be shifted to detect a minimum of sound.

S_(1) and S_(2) are two coherent sources of sound having no intial phase difference. The velocity of sound is 330 m//s . No maximum will be formed on the line passing through S_(2) and prependicular to the line joining S_(1) and S_(2) . If the frequency of both the sources is

Figure shows two line sources of sound, S_1 and S_2 separated by a distance 4 m.The two sources are in same phase at all times.The source emit same power and their lengths are also same.A detector moves along a circle with center at S_2 and radius 3m. The wavelength of the sound is 1m.When it is at A the intensity of sound due to source S_2 only is I_0 . The intensity o sound of B due to S_1 and S_2 is :
