## Mark scheme (5 marks)

1. In a transverse wave, particles oscillate/vibrate perpendicular (at right angles) to the direction of wave travel/energy transfer
2. In a longitudinal wave, particles oscillate/vibrate parallel to (in the same direction as) the direction of wave travel/energy transfer
3. Longitudinal wave described in terms of compressions and rarefactions
4. A correct example of a transverse wave given
5. A correct example of a longitudinal wave given
