(V) The vibrating string also sets the neighbouring air into vibration. State two differences between the waves on the string and those in air.

The waves on the string are _______________________ waves. And the waves ____________________________________ waves. They have different ___________________________________ but __________________________________.

(a) State the kind of wave generated on the string (transverse or longitudinal, travelling or stationary).
It is a _______________________________ wave.
(b) Find the wavelenth of the wave.

(c) Describe the motions of paricles P and Q at a period later.

At a quarter of a period later, particles P moves ___________________ and particles Q moves ____________________.
