Rubens' tube

Rubens' tube is a tube that is filled with inflammable gases and has a speaker attached to its end. The tube also has several holes in it. When the gas is lit and the speaker is set to an arbitrary frequency, the tube forms a waveform.

What is the pressure at the nodes?

High pressure Low pressure No pressure difference

The pressure at the nodes will be high.From Bernoulli principle we know that air travels from high to low pressure hence there is a surplus of inflammable air in low pressure region which we see as anti-node.
