Draw a picture of standing waves with n=3 and n=5 in a pipe with one open end. Consider the following variables: frequency f, wavelength , sound speed v, mode number n, and pipe length L. If you used the same tuning fork to create the two standing waves, which of these variables have changed between the two standing waves and which have remained the same? Explain.

help Date WS4 Sound Standing Waves I. A tuning fork is set into vibeation above a vertical open tube illed with water as shown. The wat level is allowed to drop slowly. As it does so, the air in the tube above the water level is heard to monate with the nning fork when thedstance tom the ope to he water level is at25m and again at 0.375 m. If the speed of sound in air is 343what is the...
Standing Waves in a Pipe - Both Ends Open Pattern (a) Pattern (b) Pattern (c) Pattern (d) The above figure shows standing wave patterns in a pipe whose left end is closed but the right end is open in all the patterns, the length of the pipe L = 2.10 m. The speed of sound in air is 343 m/s. You will find the wavelengths and frequencies of these standing wave patterns. (C) In Pattern (c), What is the wavelength?...
I. Draw a picture of the standing waves for each normal mode of vibration including the fundamental frequency up to n = 6 pointing to the nodes and the antinodes. II. Include in the drawing the formula of the wavelength for each case (n = 1 to n = 6) and the value of the frequency if L = 2 meters. (Remember that λ = 4L / n, where n = 1, 3, 5, 7, 9, etc.)
5. A person hums into the top of a well and hears that standing waves are established at frequencies of 42, 70, and 98 Hz. She happens to have a tuning fork with her. The 42 Hz frequency sound is not the fundamental (n 1) frequency. How deep is the well? Va 343 m/s. Hint: Overtones are the n > 1 multiples of the fundamental frequency. Determine the n 1 frequency of the well whch results in the given overtones....
6. The standing wave is formed in a tube of length L which is open at both ends. The shape of this standing wave is shown in the picture, whereas the frequency of the 5th harmonic is 450 Hz. Speed of sound is 343 m/s. Find (a) length L of the tube, and (b) harmonic’s number n; (c) wavelength, and (d) frequency of the wave shown in the picture.
Problem 4 [8 pts] A long pipe, length L, is closed at both ends, and filled with a gas with speed of sound v. The pipe is excited in some fashion in order to produce standing waves. (a) Sketch the standing wave pattern for the four lowest frequencies supported by this pipe. Label the nodes and antinodes. (b) Make a table of the wavelengths and frequencies of the sound waves that are formed by these four excitations, in terms of...
a) 266.6k b)0.353m Standing Sound Waves (16.3.10) The resonating air column in the open-closed pipe shown below is 0.635 m long. If the lowest frequency that can be produced by the pipe is 129 s'1, what is the temperature? The pipe is cut a distance d from the closed end (shown below by the dotted line) so that we now have two shorter pieces: an open-open piece and an open-dosed piece. If the second-lowest frequency that can be produced by...

(c) If one end is now closed, find the frequency of the new fundamental. 2) A piano tuner stretches a steel piano wire with a tension of 800 N. The steel wire is...
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...
