Assume that the displacement(s) of air is proportional to the pressure difference (\\Delta{p}) created by a sound wave. Displacement(s) further depends on the speed of sound (v), density of air (\\rho) and the frequency (f). If \\Delta{p}∼ 10 {Pa}, {v} \∼ 300 {m} \/ {s}, {p} \∼ 1 {kg} \/ {m}^{3} and {f} \∼ 1000 {Hz}, then {s} will be the order of (take multiplicative constant to be 1 ) [5 Sep 2020 Shift 1]

Assume that the displacement(s) of air is proportional to the pressure difference (Δp) created by a sound wave. Displacement(s) further depends on the speed of sound (v), density of air (ρ) and the frequency (f). If Δp∼10 Pa, v∼300m∕s, p∼1kg∕m3 and f∼1000Hz, then s will be the order of (take multiplicative constant to be 1 )
