Concepts covered

Wave motion
Way of transporting energy from part of space to the other without any bulk motion of material together with it is wave motion. Sound is transmitted in air in this manner.

Waves that require a medium to travel are called mechanical waves and those which do not require a medium are called nonmechanical waves.

Travelling wave or progressive wave
