Question

Mention the difference between Laplace theory and Newton’s theory.​

Answer 1

Answer:

In order to determine the speed of sound in a particular medium, we need to know the medium’s elastic properties and its density. A medium’s elastic properties determine whether or not the medium will deform or lose its shape due to external forces. Sound travels faster in mediums with high elasticity and minimal deformity – like steel. Sound travels more slowly in less rigid mediums that deform easily – like rubber. Sound travels more slowly in mediums with greater density.

Sir Isaac Newton proposed a simple formula for calculating the speed of sound. Years later Pierre-Simon Laplace would revise Newton’s formula and the new formula would be called the Newton-Laplace Equation
