In the given figure, $$S_1$$ and $$S_2$$ are coherent sources. The intensity of both sources are same. If the intensity at the point $$P$$ is $$4\ watt/m^2$$, the intensity of each source is :
Correct option is A. $$1\ W/m^2$$
Two identical speakers, emit sound waves of frequency 103 Hz uniformly in all directions.
The audio output of each speaker is 9Ļ10 mW. A point P is at a distance of 3 m from S1 and 5 m from S2. Resultant intensity of sound at P is
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 āAā² 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)
