A person standing at a distance of 6 m from a source of sound receives sound wave in two ways, one directly from the source and other after reflection from a rigid boundary as shown in figure. The maximum wavelength for which, the person will receive maximum sound intensity, is

A person standing at a distance of 6 m from a source of sound receives sound wave in two ways, one directly from the source and other after reflection from a rigid boundary as shown in the figure. The maximum wavelength for which, the person will receive maximum sound intensity, is

Intensity of sound at a point is its distance from the source

A person who is sitting at a distance of 400 m from a source of sound is listening to a sound of 600 Hz. Find the timee period between successive compressions from the source?

The sound intensity is 0.008W//m^( 2) at a distance of 10 m from an isotropic point source of sound. The power of the source is

The sound intensity is 0.008W//m^( 2) at a distance of 10 m from an isotropic point source of sound. The power of the source is

A person is standing at distance of r from a source of sound. The frequency and intensity of sound observed by him are f and I respectively. Now he moves with a uniform velocity away from sound source, then he will observers that -

A person is standing at a distance D from an isotropic point source of sound He walks 50.0 m towards the source and observes that the intensity of the sound has doubled. His initial distance D from the source is
