Answer: Transverse Wave
Explanation: A transverse wave is a type of wave for which the deformation of the medium is perpendicular to the direction of propagation of the wave. The other main type of wave is the longitudinal wave.
For example, water waves are a type of transverse wave. The water is deformed from top to bottom in the movement of the wave but the wave moves from right to left perpendicular to the direction of the deformation.
