Options are not visible though the final formula to be used in
finding the correct option is given in the attached image. All we
have to do next is just substitute values of L given and check when
the condition derived is satisfied with n as integer.
6. You can vary the length of an air column, open at one end 1 point...
Sound boxes for tuning forks are essentially pipes with one end open and one end closed. The energy of the vibrating fork builds up a standing pressure wave in the sound box. Some of the sound leaks out and makes the tuning fork more audible than it would be without the sound box. Design a box for a tuning fork at 440 Hz.
You have pipes of various lengths and openings and want to select 2 pipes (1 open-open and 1 open-closed) so your 440 Hz tuning fork will vibrate both perfectly at their first resonant points. The speed of sound in air is 343 m/s. a) What are the lengths of each of these two pipes? b) Draw a picture of the wave in both pipes and clearly indicate the nodes and antinodes of the wave inside both pipes. c) How much...

Q8: A 1024 Hz tuning fork is used to obtain a series of resonance levels in a gas column of variable length, with one end closed and the other open. The length of the column changes by 10 cm from resonance to resonance. From this data, the speed of sound in this gas is: (***) A. 205 cm/s B. 340 m/s C. 165 m/s D. 410 m/s V-(10 24)(4)(0,1) Q9: A vibrating tuning fork is held over...
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. Students in a physics lab are asked to find the length of an air column in a tube close at one end that has a fundamental frequency of 341.3 Hz They hold the tube vertically and fill it with water to the top, then lower the water while a 341.3 Hz tuning fork is rung and listen for the first resonance. A. What is the air temperature if the resonance occurs for a length of 0.2483 m? (use velocity...
1. The speed of sound in an alcohol at a temperature of 20°C is 1260 m/s. The density of the alcohol at that temperature is 650 kg/m^3. At a temperature of 20°C, find the bulk modulus of the alcohol. 1030 MPa 1080 MPa 1140 MPa 1190 MPa 1240 MPa 2. During a thunderstorm, you hear the sound 4 s after you see the lightning flash. How far did it fall? Assume the temperature outside is approximately 20 1.324 km 1.372...
Pipe A is open at both ends and has length LA. Pipe B is closed at one end and open at the other and has length LB. When both pipes produce sound in their second overtones, the result is a beat frequency of 2.5 Hz. a. Make a careful sketch of the standing wave pattern for the air displacement for each pipe. Next to each sketch write the wavelength for each pipe in terms of the pipe lengths LA...

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....
