Question

8. A student using a resonance tube determines that three resonances occur at distances of L1-0.172 m, L2-0.529 m, and L-0.885 m below the open end of the tube. The frequency of the tuning fork used is 480 Hz. What is the average speed of sound from these data?

    A resonance tube can be used to measure the speed of sound in air. A tuning fork is held above the opening of the tube and struck, while the far end of the tube is lengthened or shortened. Resonances (loudnesses) are heard at a series of tube lengths, L, which are carefully measured. resonance tube The speed of sound in air is determined by measuring the distance between two consecutive resonances. A data set for a tuning fork with a...

    If one holds an open-open tube with one end in water, one will obtain a variable length open-closed tube, the length depending on how much of the tube is immersed. Then if one holds a tuning fork over the open end of the tube, one will obtain resonances when the length, L, of the tube is such that the sound of the tuning fork will be reinforced. The smallest value of L for which a resonance occurs is 9.0 cm....

    1) Imagine you are using a closed end tube with a tuning fork having a frequency of 472 Hz in lab. You notice the second resonance point occurs when the water level is 54.0 cm from the open end of the tube. Ignoring any end correction effect, what is the speed of sound in the lab in this situation?

    The water level in a vertical glass tube 1.00 m long can be adjusted to any position in the tube. A tuning fork vibrating at 693 Hz is held just over the open top end of the tube, to set up a standing wave of sound in the air-filled top portion of the tube. (That air-filled top portion acts as a tube with one end closed and the other end open.) Take the speed of sound to be 343 m/s....

    Length of Tube A hollow tube is placed in water so that it is open at one end. A tuning fork of frequency 365-Hz is brought to one end and the length of the tube adjusted so that the sound resonates at its fundamental inside the tube. If the length of the tube is 24 cm when the tuning fork resonates, what is the temperature in the physics laboratory? (We'll ignore the effects of the tube's diameter) Hint: Find the...
