Physics
Answer
A mechanical wave is a wave that is not capable of transmitting it's energy through vacuum. They require a medium in order to transport their energy from one location to another.
Example — Sound wave.
The mechanical waves are of two types —
(a) Longitudinal waves and
(b) Transverse waves.
