Question

Explain in detail about newtons formula about speed of sound waves in air and laplace correction..DONT SPAM..

Answer 1

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.
