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 = antinodechange in frequency = decrease B) nature of displacement = antinodechange in frequency increase C) nature of displacement = nodechange in frequency increase D) nature of displacement = nodechange in frequency = decrease​

Answer 1

The correct option is "C"

The answer is

nature of displacement = node change in frequency increase
