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 minimum 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 = 1450 m s^-1 .

Find the minimum 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 = 1450 m s^-1 .

Find the minimum 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 = 1450 m s^-1 .

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.

What is the minimum distance between the reflector and the listener to hear the echo, when the speed of sound in air is 330 ms^(-1) ?

Audible frequencies have a range 20 Hz to 20,000 Hz. Express this range in terms of wavelength lambda in air. Given velocity of sound in air is 330 ms^-1 .

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 source emitting sound of frequency 180 Hz is placed in front of a wall at a distance of 2 m from it. A detector is also placed in front of the wall at the same distance from it. Find the minimum distance between the source and the detector for which the detector detects a maximum of sound. Speed of sound in air =360ms^-1 .
