Waves - Coggle Diagram

- - - - A wave with a frequency of 440 Hz has a wavelength of 0.75m. what is its speed?
        
        Figure 2
  - - - Eg. A rope is being moved up and down with a continuous vibration, taking 0.02s to complete one full oscillation. What is the frequency of this vibration?
        
        Figure 3
  - - - Eg. Find the wavenumber for a wave with wavelength of 2.0mm
        
        Figure 1
- - - - Eg. light
        
        Can travel through transparent mediums eg. atmosphere
        
        Cannot travel through opaque mediums eg. rock
    - - eg.
        
        Gamma
        
        X-ray
        
        Ultraviolet
  - - - Particles move perp. to wave direction
        
        Figure 8
      - Eg. Water ripples
      - Crests & troughs
      - Usually used to show wavelength and amplitude
      - Can only travel through a solid medium
      - Figure 7
    - - Particles of medium move parallel to wave direction
        
        Figure 6
      - Figure 5
      - Compression
        
        particles at a point are all moving towards the point
        
        Max pressure here
      - Rarefaction
        
        Particles at a point are all moving away from a point
        
        Min pressure here
      - Eg. sound waves
      - Can travel through any medium
- - - - does not just show the wave
