A string of length 0.80 m is fixed at both ends. The diagram shows a standing wave formed on the string. P and Q are two particles on the string.
The standing wave on the string creates a travelling sound wave in the surrounding air.
Outline one difference between a standing wave and a travelling wave.
[1]
travelling waves transfer energy OR standing waves don’t ✓
amplitude of oscillation varies along a standing wave OR is constant along a travelling wave ✓
standing waves have nodes / antinodes OR travelling waves don’t ✓
points in an internodal region have same phase in standing waves OR different phase in travelling waves ✓
This question was answered well. Students showed to be familiar with the differences between standing and travelling waves.
