Answer:
The movement of the particles is perpendicular to the direction of propagation.
Step-by-step explanation:
Waves are disturbances that are classified into different types. One of them is transverse waves, these waves vibrate perpendicular to their direction of motion. For example, if the direction the wave is moving is to the right, the vibration of the particles is given from top to bottom.
An example of transverse waves are electric waves and seismic waves.
