Question:
The resonance tube is filled with a liquid of density higher than that of water, then the resonating frequency
The resonance tube is filled with a liquid of density higher than that of water, then the resonating frequency
Show Hint
The resonating frequency is primarily determined by the speed of sound in the medium inside the resonance tube. Changing the density of the liquid does not affect the resonating frequency significantly.

The Correct Option is C
Solution and Explanation
Step 1: Understanding resonance frequency.
The resonating frequency in a resonance tube depends on the speed of sound in the medium inside the tube. The speed of sound in a liquid is determined by the properties of the liquid such as its density and elasticity. However, the resonance condition remains valid regardless of the change in the liquid's density, as the speed of sound in the liquid will adjust accordingly to maintain the resonance frequency. Step 2: Conclusion.
Thus, the resonating frequency will remain unchanged when the tube is filled with a liquid that has a higher density than water, which corresponds to option (C).
