Two Types of Waves
We agreed which a wave was a moving set of peaks and troughs and we used water as one example. Moving peaks and troughs, without all the characteristics we described, in any medium constitute a wave. It is possible to have waves where the peaks and troughs are perpendicular to the direction of motion, like in the case of water waves. These waves are called transverse waves.neodymium disc magnets

There are two additional types of waves. The first is called longitudinal waves and have the peaks and troughs in the same direction as the wave is moving. The question is how do we construct such a wave?

one example of a longitudinal wave is pressure waves moving through a gas. The peaks in this wave are places where the pressure reaches a peak and the troughs are places where the pressure is a minimum.

In the picture below we show the random placement of the gas molecules in a tube. The piston at the end moves into the tube without a repetitive magnet spherere-examine the NTL 2010-G05, “Decommissioning Guidance for Wells and Platforms,” to determine whether additional flexibility should be provided to better account for facility and well numbers and size, as well as timing consideration that can arise in the case of financial distress or bankruptcy of companies.

When the piston moves in it compresses the gas molecules together at the end of the tube. If the piston stopped moving the gas molecules would all bang into each other and the pressure would increase in the tube.
