What is a Mechanical Wave and a Transverse Wave?

Answer 1

http://en.wikipedia.org/wiki/Mechanical_...

A mechanical wave requires a medium. Sound waves, waves in a Slinky, and pressure waves are all examples of this term. Sound waves need air molecules in order to exist; the Slinky waves need the Slinky, and the waves in the ocean need the water.

http://en.wikipedia.org/wiki/Transverse_...

A transverse wave is a moving wave that consists of oscillations occurring perpendicular to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the yz-plane. A transverse wave could be represented by moving a ribbon or piece of string, spread across a table, to the left and right or up and down.
