In Quincke’s experiment, the sound intensity has a minimum value
Question:

In Quincke’s experiment, the sound intensity has a minimum value / at a particular position. As the sliding tube is pulled out by a distance of $16.5 \mathrm{~mm}$, the intensity increases to a maximum of $9 /$. Take the speed of sound in air to be $330 \mathrm{~m} \mathrm{~s}^{-1}$.

(a) Find the frequency of the sound source.

(b) Find the ratio of the amplitudes of the two waves arriving at the detector assuming that it does not change much between the positions of minimum intensity and maximum intensity.
