A spherical source of power `4 W` and frequency `800 Hz` is emitting sound waves. The intensity of waves at a distance `200 m` is

If a source sound of frequency 500 Hz produces waves of wavelength 0.1 m. Then the waves travel a distance of 300 m in the time in the time interval will be

A 10 W source of sound of frequency 1000 Hz sends out wave in air. The displacment amplitude a distance of 10 m from the source is (speed of sound in air = 340 m/s and density of air = 129 kg/m^(3) )

Choose the correct option? A source of frequency 500 Hz produces waves. If wavelength is 0.1 m, the waves travel a distance of 300 m in

An isotropic point source of sound waves is emitting sound waves of power 314 W in spherical wave fronts, If the sound source is located at the point ( 1 , 2 , 3 ), the intensity at point [ 4 , 6 , (3+5sqrt(3)) ], if all co-ordinates are measured in meters is :-
