A Wave - Correct answer-is something that transfers energy from one place to another 
without transferring any matter over that distance 
Longitudinal waves - Correct answer-A wave where the oscillations are parallel to the 
direction that the wave transfers energy. Examples; Sound waves, P-waves after 
earthquakes 
Transverse waves - Correct answer-A wave where oscillations are perpendicular to the 
direction that the wave transfers energy. E.g. all Electro magnetic waves on the EM 
spectrum. e...
