Answer:
The new fundamental frequency will be 598.7Hz.
Explanation:
The fundamental wavelength of the sound waves in the soda bottle is given by the equation
where is the speed of sound, and is the frequency. Since and , we have
Because it is a fundamental wavelength, the length of the soda can must be
The length of the soda bottle is 0.173 meters.
Now, if we pour 0.030 m of water, the new length of the air cavity becomes
Therefore, the new fundamental wavelength will be
,
which is a frequency of
Thus, the new fundamental frequency is 598.7Hz.
