Question

Write Newton’s Formula for the speed of sound in air. What correction was
made by Laplace in this formula?

Answer 1

Answer:

Newton's Formula for speed of sound was

$v = \sqrt{ \frac{p}{m } }$

but it was a wrong one because he thought the passing of sound through air is a isothermal process.

Laplas made it correct by adding A

$\gamma$

in his fromula..The correct formula was

$v = \sqrt{ \frac{ \gamma p}{m} }$
