Sound velocity
of any medium is that medium’s elasticity of modulus proportionate of square
root and density inverse ratio of square root.
Which medium of elasticity of modulus
is E and ρ is density in that medium of sound velocity.

Instance of
solid medium, elasticity of modulus is E=Y (Yang’s elasticity of modulus).
Hence,
Velocity
of sound in solid medium.
Again, Instance
of liquid or gaseous matters elasticity of modulus is E=K (Volume of elasticity
modulus).
Hence, Velocity
of sound in liquid or gaseous medium.

According
to Newton’s remain; sound wave of moving time is not any change in temperature
of gaseous medium. Still temperature in any gaseous or air medium is volume of
elastic modulus K in this medium pressure is equal. In other words are K=P.
Hence,
Velocity
of sound in air or gaseous medium.

\ This is Newton’s law for velocity of
sound in air or gaseous medium.
