You measured the temperature of the gas in the atmosphere and recorded 20 degree Celsius.
Remembering the valuable learning experience you had in your class Science and Technology in the
Arts, you need to determine the gas of the atmosphere on the planet Martech.
When rushing to implement the experiment, you used the sonic device to produce the three frequencies
above the resonance tube, but recorded only the length of the resonance tube that produced the first
maximum intensity for each one of them without recording the frequency of the sonic device that was
used to generate the resonance point!!!.
The lengths of the resonance tube were: 0.202m, 0.13m, and 0.256m
