waves

waves

1. transverse

   • A wave where the vibration is perpendicular to the direction of energy transfer.
   • period
     • the period of a wave is the time taken for each wave passed a fixed point.
   • T=1 over f

2. longitudinal waves

   • waves in which the vibrations are parallel to the direction of the energy transferred.
   • frequency
     • the number of waves passing a fixed point every second

3. the number of waves passing a fixed point every second Is called frequency of the waves

4. A wave length is from the middle at the top of the first wave to the middle of the top on the last wave
