A mechanical wave requires, 1. a medium (gas, liquid or solid) e.g., string, water 1. Medium MUST BE ELASTIC! à a restoring force of some sort brings the medium BACK to equilibrium after it has been disturbed e.g., the tension in a string PULLS the string back to its original position. (why it’s a SINE function and not cosine)

A mechanical wave requires, 1. 2. the particle of medium to interact with each other so that the disturbance can move from one part of the medium to the adjoining part. flickr: unloveablesteve e.g., slinky, string water, light, people
