Waves in which the medium moves in the direction perpendicular to the propagation of the wave. Waves on a stretched string, water waves, and electromagnetic waves are all examples of transverse waves.

waves such as water or slinky waves where the particles in the medium move or vibrate perpendicular to the direction of the wave.

a wave in which the disturbance (particles of the medium) making up the wave move at right angles to the direction of the propagation of the wave
