dear student,
try to get a clear idea from here,
When the energy is transferred in a transverse wave, one particle moves and is supposed to exert a pull on the nearest particles. This is key for transverse waves, but where a medium is not rigid enough, such as liquid or gas, the particles will simply slide past one another. This is why, the disturbances caused in the ocean is usually longitudinal waves, but the ones caused during an earthquake can be transverse and longitudinal waves, depending upon where the epicenter of the event falls. As seismologists started studying more on waves, they realized that longitudinal waves can travel to the core of the earth, perhaps this is why the core of the earth has molten ore.

The co-existence of longitudinal and transverse oscillations in an active filament has been reported in the experiment mentioned below:- . On March 15
th 2013, a M1.1 class flare was observed in the active region AR 11692. A CME was found to be associated with the flare. {The CME generated a shock wave that triggered the oscillations in a nearby filament}, situated at the south-west of the active region as observed from National Solar Observatory (NSO)\textit{Global Oscillation Network Group}(GONG) Hα images. In this work we report the longitudinal oscillations in the two ends of the filament, co-existing with the transverse oscillations. We propose a scenario in which {an} incoming shock wave hits the filament obliquely and triggers both longitudinal and transverse oscillations. Using the observed parameters, we estimate the lower limit of the magnetic field strength. We use simple pendulum model with gravity as the restoring force to estimate the radius of curvature. We also calculate the mass accretion rate which causes the filament motions to damp quite fast.
 
Exception, though such co-incidences do exist.
