A 30 cm violin string with linear mass density 0.625 g/m is placed near a loudspeaker that is fed by an audio oscillator of variable frequency. It is found that the string is set into oscillation o...

Two sources of sound are separated by a distance of 5.00 m. They both emit sound at the same amplitude and frequency, 300Hz, but they are 180 degree out of phase. At what point along the line conne...

A tunnel leading straight through a hill greatly amplifies tones at 135 and 138 Hz. Find the shortest length the tunnel could have.

A well with vertical sides and water at the bottom resonates at 7.20 Hz and at no lower frequency. The air in the well has a density of 1.21 kg/m3 and a bulk modulus of 1.41*105 Pa . How ...

A sound wave in a fluid medium is reflected at a barrier so that a standing wave is formed. The distance between nodes is 3.84 cm and the speed of propagation is 1520 m/s. Find the frequency.

The distance between nodes referred to in the problem means that that

$λ / 2 = 3.84 c m$ , or

$λ = 0.077 m$ . Therefore, the frequency is

$f = v / λ = (1520 m / s) / (0.077 m) 19740.25 H z$
