Waves - Coggle Diagram

- - - - Longitudinal waves are waves that travel parallel to the direction of vibrations, example include sound waves and waves in a slinky coil that is vibrated back and forth
      - Rarefactions
        
        regions of lower pressure than normal as particles are displaced further apart from each other
      - Compressions
        
        Regions of higher pressure than normal as particles are displaced closer together
    - - Transverse waves are waves that travel perpendicular to the direction of vibrations, examples include EM waves, ripples in a water tank and waves in a slinky coil vibrating across
- - - - Wave front
        
        Wave front is an imaginary horizontal line that connects all adjacent points on a wave that are in phase, and the direction of travel of the wave is always perpendicular to wave front, and the distance between successive wave fronts is wave length
      - Wave velocity
        
        Wave velocity is the distance travelled by the wave per second
      - Period
        
        Period is the time taken for 1 complete oscillation
      - Frequency
        
        Frequency is the number of complete oscillations per second
  - - - Amplitude
        
        Amplitude is the maximum possible displacement of a point from its rest position
      - Crest
        
        the crest is the highest point on a transverse wave
      - Trough
        
        a trough is the lowest point on a transverse wave
      - Wave Length
        
        wave length is the distance between 2 successive crests or troughs, and is defined as the shortest length between 2 points on a curve that is in phase, which are points with the same displacement from their rest position, speed and direction
