In general, transverse vibrations tend to have smaller frequencies than longitudinal vibrations.
2.
Here, c is a positive constant, which gives the speed at which transverse vibration waves propagate in the membrane.
3.
A string undergoing transverse vibration illustrates many features common to all vibrating acoustic systems, whether these are the vibrations of a guitar string or the standing wave nodes in a studio monitoring room.
4.
The text studies vibrations, particularly transverse vibrations of an elastic string ( chapter 7 ), longitudinal vibrations of an elastic rod ( chapter 8 ), and lateral vibrations of a thin elastic rod ( chapter 9 ).
