Two sources are placed from a person `P` as shown in figure. The speed of sound in air is `320 m//s`.
(a)
If sound signal is continuously varied from `500 Hz` to `2500 Hz`, for which frequency listener will hear minimum sound intensity.
(b)
Find the frequencies in audible range `(20-20000 Hz)` for which listener will hear maximum sound intensity.

Two stereo speakers are separated by a distance of 2.40 m. A person stands at a distance of 3.20 m directly in front of one of the speakers as shown in figure. Find the frequencies in the audible range (20-2000 Hz) for which the listener will hear a minimum sound intensity. Speed of sound in air = 320 ms^-1

Two stereo speaks S_(1) and S_(2) are separated by a distance of 2.40 m . A person (P) is at a distance of 2.40 m . A person (P) is at a distance of 3.20 m directly in front of one of the speakers as shown in Fig. 7.8. Find the frequencies in the audible range ( 20 - 20,000 Hz) for which the listener will hear a minimum sound intensity . Speed of sound in air = 320 m//s .

Find the minmimum and maximum wavelengths of sound in water that is in the audible range (20 - 20000 Hz) for an average human ear. Speed of sound in water = 1500 m//s .

A listener is at rest and a police siren is moving away from the listerner at 60m/s. what frequency does the listerner hear given that the velocity of sound in air is 340m/s and frequency os siren is 500Hz?
