In which direction of the wave motion do longitudinal waves transfer energy? O perpendicular
O parallel
O close
O equal

O parallel

Explanation:

For longitudinal waves, the direction of wave motion is parallel to the direction of their propagation.

Longitudinal waves are transferred by a series of rarefaction and compressions along their path.

One important longitudinal waves are sound waves and seismic p-waves.

Transverse waves a propagated perpendicular to the direction of their displacement.

c. orbital shape i hope this is correct
