To solve the problem, we need to find the frequency of the sound source in a Quincke's experiment, given that the sound intensity changes from minimum to minimum when the slidable tube is drawn apart by 9.0 cm, and the speed of sound in air is 336 m/s. ### Step-by-Step Solution: 1. **Understanding the Problem**: In a Quincke's experiment, the sound intensity at a point changes due to the interference of sound waves. The distance between two consecutive minima (or maxima) is related to the wavelength of the sound. 2. **Distance Between Minima**: The distance between two consecutive minima is given by the formula: \[ ...
