What is the transversal wave?

• A transversal wave is a wave where the oscillation is parallel to the direction of wave propagation.
• A transversal wave is a type of sound wave that travels through liquids.
• A transversal wave is a wave that does not require a medium to propagate.
• A transversal wave is a particles in the medium vibrate in a direction perpendicular to the direction of wave propagation.
