Q3

Figure shows two coherent line sources of sound, S1 and S2 separated by a distance 12 m. The sources emit same power and their wavelengths are also same. A detector moves along a circular path with centre at S2 and radius 4 m. The wavelength of the sound is 1 m. When it is at A the intensity of sound is Io=25 W/m2. The intensity of sound (in W/m2) at B due to S1 only is (Take S1A=9 m)

Q5

Sound from 2 identical sources S1 and S2 reach a point P. When both sounds reach in the same phase, the intensity at P due to each source is I0. The power of S1 is now reduced by 64% and the phase difference between S1 and S2 is varied continuously. The ratio of maximum to minimum intensity at P is
