How waves travel...

• Transverse waves (Up & Down Waves, Perpendicular to medium) are waves that travel in a vacuum or without air or a medium

• Longitudinal waves (Back & Forth Waves, Parallels) are waves that travel through a medium

• - Sound travels through air longitudinally

• - Seismic waves that travel through the ground travel longitudinally

• - Photon or Light waves travel through the vacuum of space transversely

Multiple Choice
