Calculate the length of a closed pipe resonator whose first harmonic is 250Hz. Assume that velocity of sound is 343m/s.
In Fig. 16-42, a string, tied to a sinusoidal oscillator at Pand running over a support at Q, is stretched by a block of mass m.The separation L between P and Q is 1.20 m, and the frequency fof the oscillator is fixed at 120 Hz.The amplitude of the motion atP is small enough for that point to be considered a node.A nodealso exists at Q. A standing wave appears when the mass of thehanging block is 286.1 g or 447.0 g, but not for any intermediatemass.What is the linear density of the string?
When a sinusoidal wave crosses the boundary between two sections of cord as in Fig. 11–34, the frequency does not change (although the wavelength and velocity do change). Explain why

- Bats of the Vespertilionidae family detect the distance to an object by timing how long it takes for an emitted signal to reflect off the object and return. Typically they emit sound pulses 3.00 ms long and 70.0 ms apart while cruising. If an echo is heard 32.8 ms later (vsound = 331 m/s), how far away is the object? When an object is only 39.2 cm away, how long will it be before the echo is heard? When an object is only 39.2 cm away, the bat __________ able to detect the echo.arrow_forwardThe windpipe of a typical whooping crane is about 5.4 feet long, what is the lowest resonant frequency of this pipe, assuming that it is closed at one end.
