Answer:
Comment on Laplace correction to Newton's formula for velocity of sound in air. ... However Laplace arged that change in pressure and volume in the region of rarefaction and compression is adiabatic as there is inadequate timefor temperature equilibrium . v=√γpρ is Laplace equation for speed of sound in air.

Laplace correction:
Since air contains mainly, nitrogen, oxygen, hydrogen etc, (diatomic gas), we take γ = 1.47. Hence, speed of sound in air is vA = ms ( 1.4 ) ( 280 ms - 1 ) = 331.30 ms-1, which is very much closer to experimental data.
Hope it helps
