Question

Why does Newton Formula fails to give the correct value of the speed of sound in a

gaseous medium?​

Answer 1

Answer:

Newton's formula for velocity of sound in gas is:

Answer:

Laplace Correction for Newton's Formula

Laplace Correction for Newton's Formula He corrected Newton's formula by assuming that, there is no heat exchange takes place as the compression and rarefaction takes place very fast. Thus, the temperature does not remain constant and the propagation of the sound wave in air is an adiabatic process.
