Q40. A first harmonic stationary sound wave is produced in the air of the cylinder, which is half-filled with water. More water is added to the cylinder, and now first harmonic stationary wave is produced with a different frequency. What is the change in frequency and nature of displacement in air at the surface of the water?Physics — Oscillations and Simple Harmonic Motion — Question 40 of 102A.
