Explanation :
Waves are the disturbance in a medium. There are many types of waves such as transverse waves, longitudinal waves etc.
In transverse waves the particles in the medium move in a direction perpendicular to the direction of energy transport or in the direction of propagation of waves.
In longitudinal waves the particles of medium travels in a direction parallel to the direction of propagation of waves.
Light waves are one of the transverse waves.
