Mechanical Wave
A wave that transfers energy through matter.
Vibration
The cyclical motion of an object about an equilibrium point
Medium
Material through which a wave travels
A medium's effectiveness of transmitting sound depends on:
1. Structure
2. Density
3. Temperature
The speed of a wave depends on:
The composition of the medium
Elasticity
The ability of a material to bounce back after being disturbed
Transverse wave
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels
Longitudinal wave
A wave in which the vibration of the medium is parallel to the direction the wave travels
Compressions
The regions of a longitudinal wave where the particles in the medium are closest together
Rarefactions
The part of a longitudinal wave where the particles of the medium are farther apart.
