The flute acts like a tube that is open at both ends. A flute
A flute can be modeled as an open-open tube. My flute is L = 0.5969 m from mouthpiece (one open end) and the end (the other open end). Assume 20 °C. a) What is the frequency of the m = 3 mode when the flute is open to atmosphere only at the two open ends? b) I lift a key that creates a hole 2V/5 from the open end. Recall that this hole opens to atmospheric pressure, as do the...
Calculate the first two modal frequencies for a flute 98.5cm long, which is open at both ends, and what are the corresponding notes?
A) A simple U-tube that is open at both ends is partially filled with a liquid of density 222 kg/m3. Water is then poured into one arm of the tube, forming a column 13 cm in height, as shown in the following diagram. The density of heavy liquid is 1000 kg/m3. What is the difference, h1, in the heights of the two liquid surfaces? Answer in units of cm. b) A simple U-tube that is open at both ends is...
A longitudinal standing wave is established in a tube open at both ends. The frequency of the standing wave is 780 Hz. What is its wavelength?
A U-shaped tube open to the air at both ends contains some mercury. A quantity of water is carefully poured into the left arm of the U-shaped tube until the vertical height \(h_{W}\) of the water column is \(22.0 \mathrm{~cm}\) as shown in (Figure 1)
A hollow glass tube A thin-walled hollow circular glass tube, open at both ends, has a radius radius R and length L (see the figure). The axis of the tube lies along the x axis, with the left end origin. The outer sides are rubbed with silk and acquire a net positive change distributed uniformly.
What is the third harmonic frequency of a 0.652 m long tube, open at both ends, on a day when the speed of sound is 340 m/s?
Suppose we have a tube with adjustable length and open at both ends. The wavelength of the fundamental mode of vibration is lambda for a given length. Suppose now that the tube is adjusted to twice the given length. What happens to the wavelength of the fundamental mode? A. It is halved. B. It is doubles. C. It quadruples. D. Can’t tell without knowing the velocity of sound in air E. Can’t tell without knowing the frequency of vibration F....
A U-shaped tube, which is open to the atmosphere on both ends, contains two liquids in equilibrium, as shown in the figure. Rank the pressures at points A, B, C and D from smallest to largest. B D
Question 13: A tube with both ends open has fundamental frequency of 300 Hz. The second harmonic of this tube and the third harmonic of another tube which is closed at one end have the same frequency. What is the length of each of these tubes? (Speed of sound 343 m s, ignore end corrections)
