The flashcards below were created by user NavjeetPuwar on FreezingBlue Flashcards. What would you like to do?


  1. Understand that for a constant wave speed the wavelength of the wave is inversely proportional to the frequency.
    For a constant wave speed the wavelength of the wave must be inversely proportionate to it's frequency
  2. The equation to calculate Wave Speed, Frequency and Wavelength of the Wave.
    • Wave Speed = Frequency x Wavelength
    •        M/S      =  Hertz, HZ x  M
    •         V        =     F          x  λ
  3. What is amplitude?
    From the middle line to the top or bottom of the arch to mark amplitude.


  4. What is wavelength and how is it calculated?
    • The wavelength of a wave is the length of one wave.
    • It is calculated using the equation; 
    • Wave speed ÷ Frequency
    •          V       ÷     F
    •          M/S    ÷     Hz
  5. What is frequency and how is it calculated?
    • Frequency is the number of waves passing through a point each second.
    • It is calculated using the equation;
    • Number Of Waves 
    •          Time

    • 1 wave per second = 1HZ
    • Frequency is measured in Hertz (HZ)
  6. What is a Wave?
    A wave is a disturbance, caused by a vibrating source, that transfer energy in the same direction as the wave is travelling without transferring matter.
  7. What is the equation used in relation to waves?
    • Distance     = Wave Speed   x    Time
    • (Metres, M) =  (M/S)            x (Seconds, S)
  8. What are transverse Waves?
    In a transverse wave, the particles vibrate at right angles to the direction of the wave's movement.

    Eg. Water Waves, S Waves, EMW Waves
  9. What are longitudinal waves?
    In a longitudinal wave, the particles vibrate in the same direction as the the moving of the wave.

    Eg. Sound Waves, P Waves
