The Wave Model
Mechanical Waves - A mechanical wave is a disturbance that travels through some material or substance called the medium for the wave.
Note: The medium as a whole does not travel with the wave.
Note: A wave transfers energy, but it does not transfer any material or substance outward from the source.
Electromagnetic and Matter Waves
Electromagnetic Waves - Electromagnetic radiation (sometimes abbreviated EMR) takes the form of self-propagating waves in a vacuum or in matter. EM radiation has an electric and magnetic field component which oscillate in phase perpendicular to each other and to the direction of energy propagation.
Matter Waves - In quantum mechanics, the matter wave, or de Broglie wave, is the wave of matter.
Transverse and Longitudinal Waves
Transverse Waves - A transverse wave is a moving wave that consists of oscillations occurring perpendicular to the direction of energy transfer.
Transverse Plane Wave
Transverse Circular Wave
Longitudinal Waves - Longitudinal waves are waves that have vibrations along or parallel to their direction of travel; that is, waves in which the motion of the medium is in the same direction as the motion of the wave.
