Two sources of sound are in resonance when

Name two sources of sound.

S_(1) and S_(2) are two sources of sound emitting sine waves. The two sources are in phase. The sound emitted by the two sources interfers at point F . The waves of wavelength :

S_(1) and S_(2) are two sources of sound emitting sine waves. The two sources are in phase. The sound emitted by the two sources interfers at point F . The waves of wavelength :

Two sources of sound are separated by a distance 4 m. They both emit sound with the same amplitude and frequency (330 Hz), but they are 180^@ out of phase. At what points between the two sources, will the sound intensity be maximum?

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

Two sources of sound produce 20 beats in 4 second. What is the difference in frequencies of the two sources?

Two vibrating systems are in resonance when

If l_1 and l_2 are the lengths of air column for two air column for two consecutive resonance position when a turning fork of frequency f is sounded in a resonance tube, then end correction is :
