Answer to Question #241100 in Physics for hassan ihtisham

Question

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, now first harmonic stationary wave is produced with a different frequency. What is the change in frequency and the nature of displacement in air at the water surface? A. Nature of displacement = antinode change in frequency=decrease B. Nature of displacement = antinode change in frequency = increase C. Nature of displacement = node change in frequency = increase
D. Nature of displacement=node change in frequency=decrease

Answer 1

Answer: C. Nature of displacement = node, change in frequency = increase
