Assume that the displacement (s) of air is proportional to the pressure difference `(Deltap)` created by a sound wave. Displacement (s) further depends on the speed of sound (v), density of air `(rho)` and the frequency (f). If `Deltap~10 Pa , v ~300 m//s,p~1 kg//m^3 and f ~1000 Hz`, then s will be of the order of (take the multiplicative constant to be 1)

A

`3/100 mm`

B

`10 mm`

C

`1/10 mm`

D
