A Mechanical wave can travel with or without medium? Explain

Answer 1

Mechanical waves are waves that require a medium in order to transport their energy from one location to another.
Because mechanical waves rely on particle interaction in order to transport their energy,
they cannot travel through regions of space that are void of particles.
