WHAT IS A WAVE?

A wave is a disturbance that moves through a medium or space.

WHAT IS A WAVE?

A wave may also be called a pulse, vibration, and/or displacement.

WAVE PULSE

A wave pulse is a single disturbance going through a medium.

WAVE MEDIUM

A wave medium is a substance which carries the wave from one location to another location.

WAVE MEDIUM

Not all waves require a medium through which to travel.

TYPES OF WAVESTYPES OF WAVES

There are 3 general types of waves: * Transverse Waves * Longitudinal or Compressional Waves * Standing Waves

TRANSVERSE WAVESTRANSVERSE WAVES

In a transverse wave the medium moves at right angles (perpendicular) to the direction the wave travels.

LONGITUDINAL WAVESLONGITUDINAL WAVES

Longitudinal waves cause matter to vibrate in the same direction (parallel) as the wave travels.

Examples of Longitudinal Waves:sound and traffic

Longitudinal waves can also be called compressional waves.

STANDING WAVESSTANDING WAVESStanding waves are generated when a series of wave pulses are sent through a medium and then reflected back upon themselves.

Parts of a Standing Wave

The nodes are places of no movement.The antinodes are places of maximum displacement from the baseline.
