Waves basics

Waves basics

1. Wave speed = Frequency x wavelength

   • V = f x λ
   • m/s = Hz x m
   • Frequency = 1/Time
     • Hz = 1/s
     • 1 wave per second = 1 Hz

2. Transverse

   • The particles move up and down around an equilibrium
     • direction of movement is at right angles to the direction of the wave

3. Longitudinal

   • particles vibrate back and forth, around an equilibrium point
   • Direction of their movement is parallel to direction of wave

4. Time period

   • is the amount of time it takes for one wave to pass a point
   • If the frequency is 4 Hz then the time period is 0.25s
