- - - - distance from one point on a wave to the some point on the next wave
    - - Frequency is the number of waves per second.
    - - distance from the centre of the wave to the highest or lowest point
      - The loudness of a sound depends on the
        amplitude.
  - - - Ultrasound is sound with a frequency higher than 20 000 Hz
- - - - parallel
        
        • The different loops of the circuit are sometimes called branches.
        
        • Parallel circuits are sometimes called branching circuits.
        
        • Ina series circuit, if one lamp breaks then all the lamps go off.
        
        • Ina parallel circuit, if one lamp breaks then the others still work.
        
        • The switch in each branch of the circuit controls the lamps in that branch
    - - Components in a parallel circuit can be turned on and off independently.
      - The current splits when it gets to a junction.
