Two sound sources `S_(1)` and `S_(2)` emit pure sinussoidal waves in phase . If the speed of sound is `350 m//s` , then
(a) for what frequencies does constructive interference occur at point `P` ?
(b) for what frequencies does destructive interference occur at point `P` ?

In experimental set up of interference the twol interfering sources S_(1) and S_(2) have an initial phase difference corresponding to a path difference of lambda//4 . The phase difference due to path difference between the twoll interfering waves at a point of constructive and destructive interference respectively is

Sound waves travel with a speed of about 330m//s . what is the wavelength of sound whose frequency is 550 hertz?

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s . The speed of sound is 330 m/s . the frequency heard by the observer will be

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s . The speed of sound is 330 m/s . the frequency heard by the observer will be

Two sound waves, originating from the same sound source travel along different paths in air and than meet at a point . The speed of the sound is 330m//s . If the source vibrates at a frequency of 500 Hz and one path is 33 cm longer than the other, then the nature of interference is -
