How Does Air Behave as Sound from a Tuning Fork Travels to a Listener?

[physics_06er]

Hi there

Can someone please check if I have answered these correctly?

A tuning fork generates a pure tone at 523Hz (v=340m/s)

...Explain what happens to the air as the sound of the tuning fork travels towards the listener?...is it right to say that compressions and rarefractions take place which corresspond to max pressure and min press. respectively.

Also it asks to sketch a graph how the air pressure varies with time at the position of the listener...is this just a sine curve?

Thanks
