The minimum intensity of sound is zero at a point due to two sources of nearly equal frequencie4s when

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

Two sources of sound are in resonance when

Two sources of sound are in resonance when

The beats are produced by two sound sources of same amplitude and of nearly equal frequencies. The maximum intensity of beats will be ...... that of one source

Two sources of sound of intensity I and 4I are used in an interference of sound experiment. Then the intensity of sound at a point where the waves from the two sources superimpose with a phase difference of (pi /2) rad is

The two coherent sources of equal intensity produce maximum intensity of 100 units at a point. If the intensity of one of the sources is reduced by 50% by reducing its width then the intensity of light at the same point will be

The two coherent sources of equal intensity produce maximum intensity of 100 units at a point. If the intensity of one of the sources is reduced by 50% by reducing its width then the intensity of light at the same point will be
