    I can't hear him properly and if someone can explain it to me that would be great. I have taken grade 12 physics.

    It basically just shows the relation between sound waves and air pressure I think?

    Sound waves are composed of compressions and rarefactions. Compressions are where the air is more dense and rarefactions are where the air is less dense. Hence the different sized flames when a standing sound wave is created in the tube.
