Answer:
Perpendicular to the motion of wave.
Step-by-step explanation:
Transverse waves are the waves that are defined as the waves whose oscillation is perpendicular to the motion of the wave.
An example of this motion is the string that produces waves by anchoring its one end and the other end will move up and down in this, the wave is propagated or its particles are moving perpendicular to the motion of the wave.
