This diagram shows some air particles as a sound wave passes.

a. On a copy of the diagram, mark:

i. A region of the wave that shows a compression–label it C

ii. A region of the wave that shows a rarefaction–label it R.

b. Describe how the particle labelled P moves as the wave passes.

c. The sound wave has a frequency of 240 Hz. Explain, in terms of the movement of an individual particle, what this means.

d. The wave speed of the sound is 320 m s⁻¹. Calculate the wavelength of the wave.
