Comment on Laplace correction to Newton's formula for velocity of sound in air.

Text Solution

Verified by Experts

Newton assumed that the isothermal condition prevails as there is adequate time for equalisation of temperature between the disturbed portion of the medium ( system ) and the rest of the air ( surrounding ) . 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 = sqrt((gamma p)/( rho ))` is Laplace equation for speed of sound in air.
