How will the fundamental frequency of a closed organ pipe be affected if instead of air, it is filled with a gas heavier than air?

What will be the effect on the fundamental frequency of a closed organ pipe if instead of air it is filled with a gas lighter than air ?

Natural gas is heavier than air.

The fundamental frequency of an open and closed organ pipe of the same length is in the ratio

the fundamental frequency of a closed organ pipe is 50 Hz . The frequency of the second overtone is

Why dry air is heavier than moist air?

The second overtone of an open pipe beats with the seconds overtone of a closed pipe with a beat frequency of 3.2 Hz. If the fundamental frequency of closed organ pipe is 120 Hz, calculate the lengths of the pipes. Take, Velocity of sound in air = 320 m/s

The gas or vapour heavier than air is

The fundamental frequency of a closed organ pipe is same as the first overtone frequency of an open pipe. If the length of open pipe is 50 cm , the length of closed pipe is

How is the fundamental frequency of an open pipe related to the fundamental frequency of a closed pipe of half the length?
