waves

waves

1. carry energy

2. carry information

3. transverse wave

   • a wave in which the medium vibrates at right angles to the direction of its propagation

4. longtitudinal wave

   • a wave in which the particle movement is parallel to the direction of the wave propagation.
     • this means that the particles move left and right which in turn makes the other particles start to oscillate

5. propagation

   • wave propagation is any of the ways in which waves travel

6. electromagnetic waves

   • they are transverse waves
   • their vibrations, or oscillations are changes in electrical and magnetic fields at right angles to the direction of wave travel.

7. sound waves

   • they are longitudinal waves
     • they are produced when something vibrates
