Lab: To Measure the speed of sound in an unknown gas


You already calculated the speed of sound in air using resonance in the laboratory. You did that by knowing the frequency of the sound, measuring its wavelength and then using the relationship

to calculate the speed.

This iLab is similar, but different in some ways:

Experimental Setup:


Please enter your name here:

Indicate which frequency of sound you want to use for this run.


Of course a single run will not give perfect results. You should run the experiment several times, put your data into a table, compute the speed for each run and then use the average speed as your conclusion:

Conclusion: the speed of sound in the unknown gas was found to be .........
