  • waves
    • waves transfer energy in the direction they are travelling without tranferring matter
    • in a transverse wave, the oscillation (vibrations)are perpendicular (at 90 degrees) to the direction of enery transfer
      • electro-magnetic e.g. light, water waves
        • waves go up and down
    • longitudinal waves the oscillation are parallel to the direction of energy transfer
      • this are sound waves in air or ultrasounds
    • frequency x wave length= wave speed
      • V= f x ?
