Speed+of+Sound

Josie Cressy and Cassie Sloma
Using 343m/s as the speed of sound, calculate 'n' (the harmonic) for various lengths and frequences.
 * Objective:**

Computer/Simulation: [|Speed of Sound]
 * Apparatus:**

1) Adjust the inner tube to desired height by dragging it with the mouse. 2) Click the "Get Ruler" button. 3) Use the ruler to measure the length from the top of the water line to the top of the inner tube. 4) Record the height. 5) Record the given frequency of the tuning fork. 6) Click the reset button and repeat steps 1-5 four times, choosing differnt lengths and frequencies for each trial. 7) Record all data.
 * Data Collection: **

1) By using the formula, f(n)=(nv)/(4L), what is the Harmonic (n) for each of the trials? 2) What effect does increasing the length of the inner tube have on n when the frequency remains the same? 3) What is the wavelength for each trial? 4) Are there any possible sources of error that could have altered the results?
 * Analysis Questions:**

Graphical Analysis is not needed for this lab due to having no actual value to compare it to.
 * Graphical Analysis:**

No precent error is needed due to having only a experimental value no actual value to compare it to.
 * Precent Error:**
